Tracheophytes, or vascular plants, have specialized tissues called xylem and phloem that allow them to transport water and nutrients throughout the plant. They are divided into three classes: ferns, gymnosperms, and angiosperms. Ferns have vascular bundles and reproduce via spores, while gymnosperms like conifers and cycads reproduce using naked seeds. Angiosperms, which include flowering plants, have fruits containing seeds and complex vascular tissue.
Kingdom Plantae
This document provides information on the classification of plants. It discusses the key characteristics of plants, including that they are multicellular organisms that can perform photosynthesis. Plants are classified into two main groups: non-vascular and vascular plants. Non-vascular plants like mosses lack transport tissues, while vascular plants have transport tissues and include seedless plants like ferns as well as seed-producing gymnosperms and angiosperms. The document goes on to describe several phyla of non-vascular and vascular plants.
Kingdom Plantae
The document describes the three divisions of bryophytes - liverworts, mosses, and hornworts. It outlines their key characteristics such as lacking true roots, stems and vascular tissue. Liverworts have a flattened thallus structure or leafy appearance. Mosses have a leafy body and reproduce asexually through budding. Hornworts are distinguished by their horn-like sporophytes. All bryophytes reproduce both sexually and asexually and play an important role as some of the earliest land plants.
Plant kingdom
This document provides information about different kingdoms of plants. It begins by listing the main kingdoms - Bryophytes, Pteridophytes, Gymnosperms, Angiosperms, and Algae. It then focuses on describing Algae in more detail, including their characteristics, reproduction methods, economic importance, and classification into three main classes: Chlorophyceae, Phaeophyceae, and Rhodophyceae. Brief descriptions are also provided for Bryophytes, Pteridophytes, and Gymnosperms.
Diversityinlivingorganisms ppt
Living organisms show a wide variety in size, lifespan, and other characteristics. To effectively study and understand such diversity, organisms must be classified into groups based on their similarities. The main characteristics used to classify organisms include their cellular structure, whether they are unicellular or multicellular, how they obtain nutrition, and the complexity of their body organization. This classification system arranges organisms in a hierarchy of nested groups from the broadest domain of life down to specific species. The five kingdom system proposed by Robert Whittaker in 1959 is still widely used, dividing organisms into Monera, Protista, Fungi, Plantae, and Animalia.
Phylum tracheophyta 2016
Phylum Tracheophyta includes vascular plants such as ferns, gymnosperms, and angiosperms. It contains plants that have true roots, stems, and leaves due to vascular tissue that transports water and nutrients. Within Tracheophyta there are four subphyla: Lycophyta containing club mosses, Sphenophyta containing horsetails, Psilophyta containing whisk ferns, and Pterophyta containing the largest group of ferns. Ferns reproduce both sexually through spores and asexually through rhizomes, with the sporophyte generation being dominant.

Introduction to Cryptogamic Botany
Organisms with hidden form of reproduction or reproductive structure. This presentation provide a comprehensive knowledge on such organisms thereby aiding to clearly distinguish them from the Phanerogams, which are organisms with and identifiable form of reproduction or their reproductive structures are identifiable.
Classification of pteridophyta
Pteridophytes are classified into 4 divisions - Psilophyta, Lycophyta, Sphenophyta, and Pterophyta. Psilophyta includes the most primitive whisk ferns and Lycophyta includes club mosses and spike mosses. Sphenophyta contains the single living genus Equisetum, or horse tails. Pterophyta, or ferns, is the largest and most widely distributed division containing many families and over 10,000 living species distributed worldwide. Each division contains multiple classes that further specify characteristics such as plant body structure, leaf and spore structures, and reproductive systems.
Plant divisions mosses and ferns
The document summarizes the characteristics and life cycles of nonvascular and seedless vascular plants. It describes two divisions of plants - nonvascular plants like moss that lack roots, stems, and leaves, and vascular plants that have transport tissues. Moss and liverworts are examples of nonvascular plants that reproduce via alternation of generations between sporophyte and gametophyte stages. Ferns are an example of seedless vascular plants that have true stems, roots, and leaves called fronds. Their life cycle also involves alternation between sporophyte and gametophyte stages. Ferns and other seedless plants were important in forming peat bogs and peat, which was used as fuel.
Classification of pteridophytes
Pteridophytes are classified into four classes: Psilopsida, Lycopsida, Sphenopsida, and Pteropsida. Psilopsida includes the oldest vascular plants with scale-like leaves and spores produced directly on the stem. Lycopsida have well-defined roots, stems, and microphyllous leaves. Spores are borne in strobili. Sphenopsida only contains the living genus Equisetum, with nodes, whorls of small leaves, and sporangiophores bearing spores. Pteropsida contains most ferns, with large megaphyllous fronds, rhizomes, and sori of sporangia
Life cycle of fern
The life cycle of ferns involves alternation of generations between a haploid gametophyte and a diploid sporophyte. The sporophyte produces spores through meiosis in structures called sori located on the underside of fern leaves. These spores develop into multicellular gametophytes that produce egg and sperm cells through mitosis. Fertilization of an egg and sperm results in a zygote that grows into a new diploid sporophyte, completing the life cycle.
Bryophytes
Bryophytes are the oldest land plants and include mosses, liverworts, and hornworts. They lack true vascular tissues and have non-lignified structures like rhizoids instead of roots. Bryophytes reproduce both sexually through the formation of gametes and asexually by forming spores. They exhibit alternation of generations where the haploid gametophyte generation is dominant. Bryophytes are ecologically important in forming peat, providing food and shelter, and indicating soil pH and acid rain levels. They also have economic uses as fuel, horticultural additives, preservatives, construction materials, and traditional medicines.
Kingdom plantae
Kingdom Plantae includes eukaryotic, multicellular organisms that are autotrophic, producing their own food through photosynthesis. They have cell walls made of cellulose and lack mobility. Plants reproduce both sexually through male and female gametes and asexually through structures like spores. They are divided into four main groups - mosses, ferns, gymnosperms and angiosperms - based on the presence of vascular tissue and seeds. Angiosperms make up the majority of plant species and their success is attributed to adaptations like specialized structures for pollination, protected seeds, and fruit aiding in seed dispersal.
Diversity in plants
Diversity is recognizing and appreciating the unique characteristics of individuals in a way that promotes achievement for both individuals and groups. Classification of plants depends on whether they have differentiated tissues for transporting water and other substances. Thallophyta include algae, fungi and lichens which may be unicellular or multicellular but lack distinct tissues. Bryophyta like mosses lack vascular tissues. Pteridophyta like ferns have sporophytes that are well developed with roots, stems and leaves. Gymnosperms are seed plants with unconcealed seeds borne in cones. Angiosperms are flowering plants with seeds contained within fruits that develop from ovaries.

The Bryophytes
Bryophytes include mosses, liverworts, and hornworts. They are non-vascular plants that lack true roots, stems, or leaves. Bryophytes reproduce both sexually through an alternation of generations involving gametophytes and sporophytes, and asexually through fragmentation or structures like gemmae. The dominant generation is the gametophyte. Mosses commonly grow in dense colonies on soil, rocks, and trees, helping to form soil and prevent erosion. Liverworts have a thallus shape and reproduce using gemmae cups. Hornworts have thalloid bodies and hornlike sporophyte projections. Bryophytes play various ecological roles and some have human uses as well.
Kingdom plantae introduction
This document provides information about the kingdom Plantae. It describes the major groups of plants including algae, bryophytes, tracheophytes, gymnosperms and angiosperms. It discusses key plant characteristics like being eukaryotic, undergoing photosynthesis, and having cell walls containing cellulose. It also explains the process of alternation of generations in plants and provides details about plant cells, photosynthesis, and the evolution of plants from single-celled algae to terrestrial plants. Specific sections cover algae characteristics, types of asexual and sexual reproduction in algae, and alternation of generations.
Plant kingdom
Plants originated from green algae in the oceans and have since colonized all environments on Earth through adaptations. They are divided into two main groups - plants without seeds like mosses and ferns, and plants with seeds including gymnosperms like conifers and angiosperms. Plants are multicellular autotrophs that produce their own food through photosynthesis, where chloroplasts in leaves use chlorophyll, water, carbon dioxide and sunlight to produce oxygen and glucose. Sexual reproduction in seed plants involves pollination transferring pollen between male and female parts, leading to fertilization and seed formation in fruits.
Chapter 22 Lecture- Plants
The document provides information about different types of plants, including their structures, life cycles, and evolutionary relationships. It discusses bryophytes like mosses which were some of the earliest plants and do not have vascular tissue. It then covers seedless vascular plants including ferns, club mosses, and horsetails, which have specialized tissues to transport water and nutrients. The life cycles of ferns are described in detail, involving alternation between haploid gametophyte and diploid sporophyte generations.
Polypodiophyta
Polypodiophyta are vascular plants that reproduce via spores and range in size from less than 1 cm to 25 m tall tree ferns. Their leaves, called fronds, are megaphylls that are typically divided into smaller segments and require external water for reproduction. Spores are released and grow into small, flat gametophytes that bear archegonia and antheridia for sexual reproduction. A zygote develops into an independent sporophyte as the gametophyte dies off. Ferns were abundant as tree ferns during the Carboniferous period 320-250 million years ago. Some modern uses include using fern fronds in floral arrangements.
Pteridophyte ppt
This document provides an overview of the general characteristics of pteridophytes. It defines pteridophytes as primitive, vascular land plants with feather-like fronds. It describes their sporophytic plant body, reproduction via spores produced in sporangia, and gametophytic generation. Key aspects covered include occurrence on land and in various habitats, vascular structure, sporangia and sporophyll types, homosporous and heterosporous conditions, antheridia and archegonia, and fertilization leading to a new sporophyte generation dependent initially on the gametophyte.
Presentation of Kingdom Plantae
The document summarizes the characteristics and classification of three divisions of land plants: Bryophyta (mosses), Pteridophyta (ferns), and Spermatophyta (seed plants). Mosses are small, non-vascular plants that play important ecological roles. They are classified into three classes. Ferns are vascular plants with compound leaves that go through four divisions. Seed plants are classified as gymnosperms, which produce naked seeds, and angiosperms, which produce seeds within an enclosure. They are an important source of food, materials, and medicines.
Pteridophytes
Pteridophytes are vascular plants and have leaves (known as fronds), roots and sometimes true stems, and tree ferns have full trunks. Examples include ferns, horsetails and club-mosses. Fronds in the largest species of ferns can reach some six metres in length!
Many ferns from tropical rain forests are epiphytes, which means they only grow on other plant species; their water comes from the damp air or from rainfall running down branches and tree trunks. There are also some purely aquatic ferns such as water fern or water velvet (Salvinia molesta) and mosquito ferns (Azolla species).
Pteridophytes do not have seeds or flowers either, instead they also reproduce via spores.
There are around 13,000 species of Pteridophytes.
Kingdom plantae
This document discusses the classification of plants. It divides plants into two main groups: non-vascular plants (bryophytes) and vascular plants (tracheophytes). Non-vascular plants lack specialized tissues for transporting water and nutrients. They are small and need wet environments. Vascular plants have tissues like xylem and phloem that allow transport of water and nutrients. They are further divided into gymnosperms, which produce naked seeds, and angiosperms, which produce flowers and fruits containing seeds. Key groups discussed include ferns, conifers like pine trees, and flowering plants.
Phylum lycophyta (Club mosses, Spike mosses & Quillworts)
The document discusses the phylum Lycophyta. It describes Lycophyta as the oldest living lineage of vascular plants, with three orders: club mosses, spike mosses, and quillworts. The dominant generation in Lycophyta is the sporophyte, which reproduces through spores. Club mosses, spike mosses, and quillworts each have unique characteristics and life cycles. Lycophytes also have economic and ecological importance.
cyptogams vs phanerogams
Cryptogams are plant groups that reproduce via spores rather than seeds, including algae, lichens, mosses and ferns. They have hidden reproductive organs and represent non-seed bearing plants. The main cryptogam groups are thallophytes, bryophytes and pteridophytes. Examples include mosses, liverworts, and ferns.
Kingdom Plantae
The document discusses key aspects of the kingdom Plantae. It defines plants as autotrophic, multicellular eukaryotes that have cell walls. The document outlines the main parts of a plant cell, including the nucleus, cell wall, cell membrane, chloroplasts, and vacuole. It also discusses how plants survive on land by obtaining water and nutrients, retaining water, transporting materials, and reproducing sexually through fertilization. Plants are classified as either nonvascular, which lack a well-developed transportation system, or vascular, which have a well-developed system to transport water and materials. Examples of nonvascular and vascular plants are provided. The life cycle of plants involves a sporophyte and gametophyte
Biotin ..
Biotin is a water-soluble B vitamin that acts as a coenzyme in carboxylation reactions involved in metabolizing fats and amino acids. It is found naturally in foods like peanuts, Swiss chard, and eggs, and supports cell growth, metabolism, blood sugar levels, and healthy hair and skin. A biotin deficiency can result from genetic errors affecting biotin-related enzymes and may cause alopecia, conjunctivitis, dermatitis, depression, lethargy, or numbness and tingling.

Biotin is a water-soluble B vitamin that acts as a coenzyme in carboxylation reactions in the body. It is not synthesized in humans and must be obtained through dietary sources like eggs, liver, and leafy greens. Biotin helps convert pyruvate to oxaloacetate in gluconeogenesis, convert acetyl-CoA to malonyl-CoA in fatty acid synthesis, and is important for cell division and growth. Biotin deficiency can occur due to genetic defects impairing biotin absorption or through excessive raw egg consumption, which contains the biotin-binding protein avidin. Deficiency can cause skin rashes, hair loss, neurological issues, and fatty acid
Biotin
Biotin is a B vitamin that acts as a coenzyme in carboxylation reactions in the body. It is found naturally in many foods like nuts, dairy, eggs, and vegetables. In the body, biotin functions to help metabolize fats and amino acids. It also plays roles in immune function, hair and nail growth, and healthy skin. Deficiencies can result from raw egg consumption due to biotin binding by the protein avidin in eggs. Biotin is used diagnostically to detect deficiencies and in techniques like ELISA and DNA labeling using its strong binding to avidin and streptavidin.
Biotin ppt.
Biotin is a B vitamin that acts as a coenzyme in carbohydrate, protein, and lipid metabolism. It is essential for cell growth and DNA/RNA replication. Biotin deficiency can cause dermatitis, hair loss, and neuromuscular dysfunction with symptoms like scaly skin, rash, hypotonia, and depression. Good dietary sources of biotin include eggs, organ meats, nuts, dairy, and whole grains.

An Introduction to the Science of Botany
OBJECTIVE:
Briefly describe the field of botany, and give short definitions of at least five subdisciplinesof plant biology
Botany an overview
Botany is the study of plants. It includes the study of bacteria, viruses, fungi, algae, bryophytes, pteridophytes, gymnosperms and angiosperms. Some key points covered in the document include:
- Bacteria and fungi have economic importance as both harmful and useful organisms. They are involved in food production and cause diseases.
- Viruses only infect plants and humans, causing diseases. Fungi grow on decaying organic matter and have edible and poisonous forms.
- Algae are important producers and are used as food and in industry. Bryophytes and pteridophytes include mosses and ferns
Happy Lantern Festival
The Chinese Lantern Festival, also known as Yuan Xiao Jie, occurs on the 15th day of the first lunar month of the Chinese calendar. According to legend, the Jade Emperor planned to destroy a town with fire for killing his favorite goose, but a fairy told the townspeople to light lanterns around the town to make it appear it was already burning. When the Jade Emperor saw the "fire", he believed the town had already suffered and called off the firestorm. Now people celebrate by carrying colorful lanterns outside and releasing sky lanterns with wishes written on them. Traditional foods eaten include tangyuan, sticky rice balls in sweet soups.
SCRABBLE - MAPEH 8 (Physical Education 3rd Quarter)
Scrabble is a word game where players score points by placing tiles with letters onto a game board to form words. It was invented in the 1930s and became popular internationally. Players draw letter tiles and take turns adding letters to the board to form new words crosswise or horizontally by connecting to existing letters. Scoring is based on the letters and any premium squares; the player with the highest score at the end of the game wins.
Vitamin b7 (biotin)
Vitamin B7, also known as biotin or vitamin H, is a water-soluble vitamin important for metabolism. It is involved in fatty acid, carbohydrate, and protein metabolism as well as glycogen synthesis. Deficiencies are rare as biotin is found widely in foods and small amounts can be synthesized by intestinal bacteria. However, avidin in raw egg whites can bind biotin and make it unavailable. Adequate intake levels for adults are 30 mcg per day for men and 25 mcg for women. Biotin supports healthy skin, hair, nails and metabolism. Deficiency can cause brittle nails, hair loss and neurological symptoms.
Present Loy Krathong Festival
Loy Krathong Festival is a Thai festival held on the full moon of the 12th month in the traditional Thai lunar calendar, usually in November in the Western calendar. During the festival, people float small rafts called krathong, made of banana leaves and decorated with flowers and candles, down rivers and canals to honor the goddess of water. The festival includes beauty pageants, fireworks, and the tradition of carving vegetables. It began in Sukhothai but is now celebrated nationwide, particularly in Chiang Mai where sky lanterns are also launched into the air.
Kto12 4th arts nang shadow puppets of thailand
Shadow puppets called Nang are a traditional form of entertainment in southern Thailand, performed with intricately cut leather puppets manipulated on rods. Performances draw from religious and epic stories and current events, conveying Thai values through allegories. Skilled puppeteers narrate using different voices while hiding behind the screen, entertaining audiences from dusk to dawn with rhythmic storytelling.

Overview of Green Plants
1) Green plants include land plants and green algae. Land plants evolved from a group of freshwater charophyte algae and have multicellular haploid and diploid phases with protected embryos.
2) Plants have a life cycle with alternation between a multicellular diploid sporophyte generation that produces haploid spores and a multicellular haploid gametophyte generation.
3) Major groups of land plants include bryophytes (non-vascular), lycophytes and pterophytes (vascular non-seed plants), and seed plants including gymnosperms and flowering plants.
Charleen Baker - Botany Lecture - Lecture
The document discusses the characteristics, life cycles, and ecological importance of nonvascular plants including mosses, liverworts, and hornworts. It describes their adaptations for terrestrial environments like specialized water conducting cells and cuticles. The alternation of generations between haploid gametophytes and diploid sporophytes allows for sexual reproduction even on land.
Kingdoms.ppt
The document discusses taxonomy and the classification of organisms. It describes the six kingdom system including Bacteria, Archaea, Protista, Plantae, Fungi, and Animalia. Prokaryotes are organisms that lack a nucleus, while eukaryotes have cells with nuclei. The kingdoms of Bacteria and Archaea only contain prokaryotes. The kingdoms of Fungi and Animalia only contain heterotrophic organisms.
Plant Phyla
The document summarizes four main plant phyla: Bryophyta (mosses), Pteridophyta (ferns), Gymnosperms (conifers), and Angiosperms (flowering plants). It provides details on the characteristics and life cycles of mosses, ferns, and conifers. Mosses are non-vascular plants that rely on moisture for transport and help prevent erosion. Ferns have vascular tissue but reproduce via spores. Conifers reproduce via naked seeds in cones and have needle-like or scale-like leaves. The document then states it will provide details on important angiosperm families.
Diversity in living organisms by HVJ
This document provides an overview of the five-kingdom classification system used to categorize different types of living organisms, with a focus on the plant kingdom. The key characteristics used to classify organisms are whether their cells are prokaryotic or eukaryotic, unicellular or multicellular, and whether they have cell walls or can perform photosynthesis. Within the plant kingdom, the main subdivisions discussed are thallophyta (algae and fungi), bryophyta (mosses and liverworts), pteridophyta (ferns), gymnosperms (conifers and cycads), and angiosperms (flowering plants). Examples and brief descriptions are provided for each group.
Vascular Plants: Pteridophyta (part 1)
Pteridophyta or Pteridophytes are Vascular Plants (also known as "seedless plants") that reproduce and disperse via spores. They do not produce either seeds or flowers.
Additional info:
+ Division Equisetophyta (horsetails & scouring rushes)
+ Division Psilotophyta (whisk ferns)
(This is our report in Botany 2.)
Made by: Sharmine Ballesteros (BS Biology 2A2-1)
Plant biology
This document discusses the key characteristics of plants in the kingdom Plantae. It outlines that plants are multicellular eukaryotes that perform photosynthesis, have cell walls made of cellulose, and store carbohydrates as starch. It also describes some of the obstacles plants have overcome to thrive on land, such as developing vascular systems to transport water and nutrients, cell walls, cuticles, and stomata to conserve water. The document divides plants into nonvascular and vascular divisions and discusses their alternation of generations life cycle and reproductive structures.
Groups, phyla, classes
The document outlines 10 major groups of plants classified by their phyla. It describes the key characteristics of each phylum including their common names, estimated number of species, distinguishing physical attributes, and some additional details. The phyla cover major kingdoms of plants such as nonvascular plants (Bryophytes), seedless vascular plants, gymnosperms, and angiosperms.
Nymphalidae , Pieridae , Lycaenidae complete details (Butterfly families)
This summarizes the key information about the Nymphalidae family of butterflies:
1) Nymphalidae is the largest family of butterflies, with over 6,000 described species. It includes well-known butterflies like monarchs and painted ladies.
2) Nymphalid butterflies are often called "brush-footed" because the front pair of legs are small and brush-like, used for sensing rather than walking.
3) Species in this family can be found on every continent except Antarctica, and occupy a wide range of habitats from forests to deserts. They have diverse food sources including flowers, tree sap, and dung.
DIVERSITY IN ORGANISMS
This document discusses diversity in living organisms. It describes four types of diversity: point diversity, alpha diversity, gamma diversity, and epsilon diversity. It then explains the five-kingdom classification system of Monera, Protista, Fungi, Plantae, and Animalia. Within each kingdom, various phyla and examples are outlined. The document focuses in depth on the plant and animal kingdoms, describing their classifications and key characteristics.
Diversity in living organisms
This document discusses diversity among living organisms. It describes four types of diversity: point diversity, alpha diversity, gamma diversity, and epsilon diversity. It then explains the five-kingdom system of classification for organisms - Monera, Protista, Fungi, Plantae, and Animalia. Each kingdom is further divided into smaller subgroups like phylum, class, order, family, genus and species. The key characteristics of each kingdom are outlined. The plant and animal kingdoms are described in more detail with their various divisions.
The plant kingdom (alage+bryophyta+pteridophyta)
This document describes characteristics of bryophytes and their importance. It discusses:
1. Bryophytes include mosses, liverworts and hornworts which reproduce via alternation of generations between a haploid gametophyte and diploid sporophyte generation.
2. They play important roles through peat formation, use as fuel and horticultural additives, and in providing seed beds, food and shelter.
3. Bryophytes also serve as indicators of environmental conditions like soil pH and acid rain, and have some medicinal uses.
Diversity of flowering plants deals pptx
Flowering plants show immense diversity in their morphology, ecology, taxonomy, and phylogeny. They range in size from the tiny duckweeds less than 2 mm wide to Eucalyptus trees over 100 m tall. Most are photosynthetic, though some are parasitic on fungi or other plants. They occupy nearly all land and aquatic habitats. Taxonomically, there are over 300,000 known species classified into 64 orders and 416 families. The Ranunculaceae family includes over 2,500 herbaceous species, many with showy flowers and compound leaves. Clematis is a notable genus of over 380 climbing species.
project in science
Nonvascular plants lack true roots, stems, and leaves due to the absence of vascular tissue. They are called thallophytes and include mosses, liverworts, and hornworts. They must live in moist environments because they lack internal structures for transporting water and nutrients and generally only grow 1-2 cm tall. Vascular plants have specialized tissues for transport and include both spore-bearing plants like ferns and seed-bearing plants like gymnosperms and angiosperms. Gymnosperms produce naked seeds enclosed in cones while angiosperms produce seeds enclosed within flowers in an ovary.
Chapter 25
All land plants evolved from a single species of freshwater green algae that colonized land over 1 billion years ago. Early land plants like bryophytes and non-vascular plants developed adaptations like an alternation of generations lifecycle and protective structures to survive on land. Vascular plants then evolved xylem and phloem tissues for transport which allowed them to grow larger. Seed plants later evolved seeds for protection and dispersal.
bryophytes and pteridophytes.ppt cryptogams
This document discusses cryptogams, which are early non-vascular land plants. It presents the hypothesis that all plants evolved from ancient green algae based on shared traits like chloroplasts, cellulose cell walls, and starch storage. Bryophytes like mosses, liverworts, and hornworts are described as the first land plants, lacking true roots and vascular tissue. Their life cycles involve a dominant haploid gametophyte phase and a dependent diploid sporophyte phase. Classification systems for different bryophyte groups are also outlined. Pteridophytes represent the next stage of land plant evolution with differentiated roots, stems, and leaves, but lacking seeds.
Fern
Ferns reproduce through an alternation of generations, where they have both a sporophyte and gametophyte stage. The sporophyte produces spores that grow into the gametophyte plant, which produces eggs and sperm. When an egg is fertilized by sperm, it grows into a new sporophyte plant, completing the life cycle. Ferns reproduce using these spores rather than flowers, fruits, or seeds. They have sori clusters on their leaves undersides that contain sporangia holding the reproductive spores.
Gymnosperms
Gymnosperm is from the Greek “gymnos” naked, and “sperma” seeds. They are groups of vascular plants that reproduce by means of an exposed seeds or ovules. They are phanerogams according to A. W. Eichler.
Plant Kingdom.pptx
The Plant Kingdom is characterized by autotrophic organisms that produce their own food, have cell walls, chloroplasts, and vascular tissue. Plants are classified based on their plant body, vascular system, and seed formation. The divisions include cryptogams (non-flowering) such as algae, fungi, lichens, bryophytes, and pteridophytes, as well as phanerogams (seed-bearing) such as gymnosperms and angiosperms. Angiosperms are further divided into monocots and dicots.
Rhodophyta
This document provides information about the red algae (Rhodophyta). It discusses the key characteristics of red algae such as their pigments, food storage, and lack of flagella. It then describes the classification system of Rhodophyta and provides details about 6 orders within the subclasses Bangioideae and Florideae. For each order, 1-2 examples are given and their characteristics summarized such as reproduction methods and habitat. The document concludes with references used.

Climate Change All over the World .pptx
Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
Recycling and Disposal on SWM Raymond Einyu pptx
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

- 1. Kingdom Plantae-Pteridophyta Diversity in living organisms By : Preksha and Ramla
- 2. Criteria for kingdom plantae •Cell type : Eukaryotes. •Cell number:multicellular •Cell structure :cell wall made of cellulose •Mode of nutrition: autotrophic •Some are parasitic or saprobes
- 3. Pteridophyta a division of flowerless green plants that comprises the ferns and their relatives. Examples include ferns, horsetails and club-mosses. Many ferns from tropical rain forests are epiphytes, which means they only grow on other plant species. Fronds is the largest species of ferns it can reach some six metres in length!
- 4. WHAT IS CRYPTOGAMAE? A cryptogam (scientific name Cryptogamae) is a plant that reproduces by spores, without flowers or seeds.
- 5. TYPES OF PTERIDOPHYTES Pteridophytes have mainly been divided into 3 Classes. • Lycopodophyta (club mosses) • Sphenophyta (horse tails) • Filicinophyta (ferns)
- 6. CLUB MOSSES • The plants are mainly native to tropical mountains but also common in northern forests of both hemispheres. • Club mosses are evergreen herbs with needlelike or scale like leaves and, often, cone like clusters of small leaves (strobili), each with a kidney-shaped spore capsule at its base. • They do not have seeds.
- 7. HORSE TAIL • The plants grow in wetlands and marshy, wet areas at the edge of swamps, ponds and lakes. • Horsetails are vascular plants that reproduce by spores, not seeds, and by spreading underground stems called Rhizomes. • The common field horsetail is a perennial that grows up to 2 feet tall.
- 8. FERN • Ferns are vascular plants. • They have roots and leaves (called fronds) and in some cases they have true stems. • Ferns can be deciduous or evergreen. • In tropical regions, tree ferns may reach a height of 80 feet.
