Algae are photosynthetic organisms that contain chlorophyll as their primary pigment and lack a sterile cell covering around their reproductive cells. They are classified into different types including euglenophyta, pyrrophyta, chlorophyta, rhodophyta, and paeophyta. The classification of algae is based on the same rules as for land plants but above the order level has changed substantially since 1960 due to differences observed using electron microscopes. Algae belong to the plant and monera kingdoms, with green, brown, and red algae in the plant kingdom and cyanobacteria in the monera kingdom.

Algae
Algae are a diverse group of aquatic organisms that have the ability to conduct photosynthesis. Certain algae are familiar to most people; for instance, seaweeds (such as kelp or phytoplankton), pond scum or the algal blooms in lakes.
ALGAE General Characters
1. Algae are simple, autotrophic plants that lack differentiation into tissues. They can be unicellular or multicellular and are found in aquatic, terrestrial, and unusual habitats.
2. Algae thalli are either unicellular or form colonies, filaments, or pseudoparenchymatous structures. Unicellular algae can be flagellated, amoeboid, or non-motile coccoidal forms. Multicellular thalli include colonies, branched and unbranched filaments, and pseudoparenchymatous forms.

Algae report
Algae are a diverse group of simple plant-like organisms ranging from unicellular to multicellular forms. They are typically photosynthetic and aquatic, lacking true roots, stems, leaves, and vascular tissue. Algae are classified into several divisions including green algae, red algae, brown algae, diatoms, dinoflagellates, and cyanobacteria (blue-green algae). Each division contains many distinct species that vary in habitat, structure, pigmentation and other characteristics. Algae play an important role as primary producers in many ecosystems.

Classification of Algae
Algae are a diverse group of photosynthetic organisms that can be unicellular or multicellular, and are classified into 11 classes based on characteristics like pigmentation and type of flagella. Their life cycles vary but include haplontic, diplontic, isomorphic, and heteromorphic types, with some exhibiting alternation between haploid and diploid generations while others reproduce asexually. Major classes discussed are Chlorophyceae, Xanthophyceae, Bacillariophyceae, Phaeophyceae, Rhodophyceae, and Myxophyceae.
phycology-algal classification, thallus organization, reproduction
The document discusses phycology, the study of algae. It covers the classification of algae based on characteristics like pigmentation and thallus organization. Some key classifications discussed include Harvey's 1836 system of dividing algae into green, brown and red classes, and Fritsch's 1935 classification that organized algae into 11 classes. The document also summarizes the distribution of algae in aquatic environments, their thallus organization as unicellular or multicellular, and their methods of reproduction including vegetative, asexual through spores, and sexual.
Similarities and dissimilarities of algae and plants
Algae and plants share some similarities such as both undergoing photosynthesis and having chloroplasts with chlorophyll. However, they also have key differences. Algae typically live in water and are unicellular or simple multicellular organisms lacking roots, stems, and leaves. In contrast, plants have evolved to live on land and are complex multicellular organisms differentiated into these specialized structures. While both reproduce sexually, algae do not form embryos like plants.
Algae introduction-characters
Algae are primitive, chlorophyll-containing plants that live in both aquatic and terrestrial environments. They can be microscopic (microalgae) or macroscopic (macroalgae). Algae have undifferentiated thallus-like bodies and reproduce through both asexual and sexual means. They are divided into groups based on their pigments, which include chlorophylls, carotenoids, and phycobilins.
Economical importance of algae
Beneficial and Harmful use of Algae.
Algae is used as food, fodder, medicines, production of agar agar, antibiotics etc.
Algae seminar
This document is a report on algae written by Bhargavi Dutta for her M.Sc in Biotechnology. It discusses the key characteristics and types of algae. Algae are a diverse group of photosynthetic organisms that live in water and vary in size from microscopic to large seaweeds. They are classified based on their color, food storage product, structure and reproduction. The five main types of algae are diatoms, green algae, blue-green algae, brown algae, and red algae. Algae play an important ecological role and also have applications in areas like biofuels and food additives.
Algae
Algae range in size from microscopic to over 700 feet long. They are photosynthetic organisms that can be unicellular or multicellular. Algae reproduce both sexually and asexually and are classified into phyla based on their pigments, food storage, and cell wall composition. The major phyla are brown, red, and green algae. Algae are ecologically important as primary producers and oxygen generators. They also have many uses including food, hydrocolloids, fertilizers, and wastewater treatment.
Evolutionary history
Land plants evolved from green algae, specifically from a group of green algae called charophyceans that share many characteristics with modern land plants. Coleochaete, a type of green alga, is probably the closest living relative to the extinct algal ancestor of land plants and provides insights into what the transition from aquatic to terrestrial environments may have looked like. Coleochaete exhibits traits like a compact thallus that would help it survive out of water and may represent an intermediate form in the evolution of plant spores and meiosis.
Rhodophyta by sohail hashmi
This document provides information about Rhodophyta (red algae). It discusses that red algae are a phylum of multicellular eukaryotic algae that are predominantly marine. They are one of the oldest algal groups dating back to the Cambrian period. Red algae have complex life cycles and can reproduce both sexually and asexually. They are a source of important polysaccharides like agar and nori seaweed is eaten in Japan. Red algae also play a role in coral reef formation.

This document summarizes the different types of thallus organization found in algae. It describes unicellular forms that can be motile or non-motile, and discusses colonial forms that can be motile or non-motile. It also outlines various filamentous forms including unbranched, branched simple, heterotrichous, and pseudoparenchymatous filaments. Additionally, it mentions siphonaceous forms, parenchymatous forms, and concludes with a thank you message.
Algae.pdf
The term "algae" refers to a class of mostly watery, photosynthetic, and nucleus-bearing organisms that lack the real roots, stalks, and leaves of plants as well as their specialized multicellular reproductive systems.
What are Algae?
In addition to ponds, brackish waterways, and even snow, seaweed may be found in rivers, lakes, seas, and ponds. seaweed are often green, although they can also be found in other hues. For instance, the carotenoid pigments and chlorophyll present in the seaweed that live in snow give the surrounding snow its unique red colo The name "alga" refers to a huge and extraordinarily diversified class of eukaryotic, photosynthetic lifeforms. These species are not linked to one another (polyphyletic) since they do not have a common ancestor.
Giant kelp and brown algae are two examples of multicellular algae. Examples of unicellular organisms include dinoflagellates, euglenophytes, and diatoms.
Since most algae need a moist or wet environment to thrive, they can be found everywhere near or inside water bodies. They have anatomical similarities with the land plants, a significant group of photosynthetic creatures. The distinctions stop there since seaweed lack many of the structural elements that are generally seen in plants, such as real stems, shoots, and leaves. Additionally, they lack the vascular tissues needed to transport vital nutrients and water throughout their bodies.
Characteristics of Seaweed
Plants and animals share specific general properties of seaweed.
Eukaryotic cells make up seaweed. Algae, for example, may photosynthesize like plants and have specialized cell organelles like centrioles and flagella that are exclusively found in animals. Manna's, cellulose, and Galatians make up the algal cell walls. Some of the general characteristics of algae are listed below.
Seaweed are photosynthetic organisms
Seaweed can be either unicellular or multicellular organisms
Seaweed lack a well-defined body, so, structures like roots, stems or leaves are absent
seaweed are found where there is adequate moisture.
Reproduction in algae occurs in both asexual and sexual forms. Asexual reproduction occurs by spore formation.
Seaweed are free-living, although some can form a symbiotic relationship with other organisms.
Types of Saweed
Algae come in a variety of varieties. But these are a few of the more well-known kinds:
Red Scum
It is a peculiar species that is also known as Rhodophyta, and it may be found in both freshwater and marine settings. The distinctive red hue of the algae is caused by the pigments phycocyanin and phycoerythrin. There are other pigments that give things their green hue, such chlorophyll a. But neither beta-carotene nor chlorophyll B are present.
Green Algae
It is a large, loosely organized collection of scum that include the essential pigments for photosynthetic activity, chlorophylls A and B, as well as auxiliary pigments like xanthophyll's and beta carotene.

Microbiology - Algae
Algae is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades.
Algae are sometimes considered plants and sometimes considered "protists" (a grab-bag category of generally distantly related organisms that are grouped on the basis of not being animals, plants, fungi, bacteria, or archaeans).
Bga & azolla
Blue-green algae, also known as cyanobacteria, are photosynthetic bacteria that produce oxygen. They possess chlorophyll and can fix nitrogen. Azolla is an aquatic fern that has a symbiotic relationship with nitrogen-fixing cyanobacteria. It grows easily and can be used as green manure to improve soil nutrition. Both blue-green algae and Azolla are important for agriculture - blue-green algae fix nitrogen while Azolla acts as a biofertilizer when used in rice fields and on other crops.

It begins by explaining phylogenetic, numerical, cytotaxonomy, and chemotaxonomy classification systems. It then describes key characteristics of different algal divisions - Chlorophyceae, Phaeophyceae, and Rhodophyceae. The document also summarizes reproduction in algae and provides examples of economically important algae.
2.D Algae
The document discusses the classification of microorganisms, focusing on algae. It describes how algae are classified into five lineages based on molecular evidence, instead of the previous seven-division system. Key details include:
- Algae are classified into divisions (Chlorophyta, Charophyta, etc.) based on features like cell structure, pigments, food storage, habitat, and reproduction.
- Chlorophyta (green algae) include Chlamydomonas, Chlorella, and Volvox and have chloroplasts with starch storage.
- Diatoms have a distinctive silica cell wall called a frustule and reproduce asexually, getting smaller over generations.
Algae classification
This document discusses the classification, characteristics, and economic importance of algae. It begins by outlining Linnaeus' original classification of algae in 1753 and notes that many algae are unicellular. It then discusses the morphology, pigments like chlorophyll and carotenoids, and cell structure of algae including chloroplasts and thylakoids. The three main groups - green, red, and brown algae - are classified based on their primary pigments, storage products, cell wall composition, and flagella. Examples of commonly known algae from each group are also provided. The document concludes by explaining the economic importance of algae as primary producers and sources of commercial products like agar, alginic
Nomanclature of microbes
This document discusses the classification of different types of living organisms. It covers the six kingdoms of life - Archaea, Bacteria, Protista, Fungi, Plantae, and Animalia. It describes key characteristics of bacteria, archaea, protists, fungi, plants, animals, and viruses. The classification systems are meant to group organisms based on similarities to better understand and study life forms.
Archea and bacteria paragraphs
The document discusses four kingdoms of Archaea: Korarchaeota, Euryarchaeota, Crenarchaeota, and Nanoarchaeota. It also discusses several groups of bacteria, including Proteobacteria, Chlamydias, Spirochetes, Cyanobacteria, and Gram-positive bacteria. Key details provided include that Korarchaeota are only found in high temperature environments, Euryarchaeota include methanogens and halobacteria, Crenarchaeota were thought to be extremophiles but are also found in marine environments, and Nanoarchaeota are the smallest recently discovered in deep sea vents.
Get to know algae
- Algae are a diverse group of photosynthetic organisms ranging from unicellular to multicellular forms like giant kelp. They lack complex tissues and organs found in land plants.
- Algae are classified as eukaryotes and conduct photosynthesis within membrane-bound chloroplasts. Their chloroplasts differ depending on endosymbiotic events in their lineages.
- Some algae form symbiotic relationships where they supply photosynthates to host organisms in exchange for protection, such as in lichens and coral reefs.
Plant Biodiversity classifications life cycles.pptx
The document discusses plant biodiversity and classification. It covers several kingdoms of plants including algae, bryophyta, pteridophyta, and gymnosperms. For each kingdom, it describes key characteristics such as plant structure, life cycles, and examples of types of plants. It also discusses economic importance for some kingdoms.
Classification of Algae
General characteristics of Algae,Basis for the classification of Algae,Fritsch classification of algae,Van den Hoek (1995) classified algae into 11 divisions,Chlorophycophyta – The green algae,Rhodopycophyta-The red algae,Cryptophycophyta-The cryptomonads,Euglenophycophyta-The euglenoids,Chrysophyciphyta –The Golden brown algae.

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.

Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...
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.

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.

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.

BASIC CONCEPT OF ENVIRONMENT AND DIFFERENT CONSTITUTENET OF ENVIRONMENT
BASIC CONCEPT OF ENVIRONMENT AND DIFFERENT CONSTITUTENET OF ENVIRONMENT
Algae
- 2. Definition The bacteria which has chlorophyll as their primary photosynthetic pigment and lack a sterile covering of cells around their reproductive cells is called as ALGAE.
- 3. TYPES OF ALGAE Euglenophyta (Euglenoids)
- 9. Chrysophyta (Golden-brown algae and Diatoms)
- 10. CLASSIFICATION OF ALGAE The classification of algae into taxonomic groups is based upon the same rules that are used for the classification of land plants, but the organization of groups of algae above the order level has changed substantially since 1960. Early morphological research using electron microscopes demonstrated differences in features, such as the flagellar apparatus, cell division process, and organelle structure and function, that have been important in the classification of algae.
- 11. KINGDOM OF ALGAE Algae belongs to kingdom Plantae, though they are photosynthetic autotrophic organisms. Blue green algae or cyanobacteria belong to kingdom Monera. Green ,Brown and Red algae belong to Plant kingdom
