Algae are either plants or protists that live in or near water. They lack specialized root, stem, and leaf structures and must live in water to obtain nutrients and oxygen and remove waste through diffusion rather than an internal transport system. Adaptations for living in water include being thin enough not to dry out and having simpler reproductive cycles where gametes can swim to fertilize each other. Their divisions are categorized based on their pigments.
Algae are eukaryotic organisms that live in aquatic and moist environments. They can be unicellular or multicellular. Unicellular algae are most common in water and plankton. Algae have chloroplasts and photosynthesize but some obtain energy chemically. They store food as starch and reproduce through both asexual and sexual methods like fragmentation, spores, and fusion of gametes.
Algae are simple aquatic plants that can be unicellular or multicellular. They are classified in the kingdom Protista and are divided into five main groups. Algae can be found in both marine and freshwater environments. They use photosynthesis to produce food and oxygen. Some key points about algae include:
- They come in many forms including unicellular, colonial, filamentous, and multicellular bodies
- Reproduction can occur sexually through gametes or asexually through fragmentation, spores, or binary fission

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 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.
Algae are a diverse group of photosynthetic organisms that can range in size from microscopic to large seaweeds. They are classified into seven phyla based on characteristics like color, chloroplast contents, and cell wall composition. Algae reproduce both sexually through meiosis and asexually through mitosis. The most common forms of sexual reproduction include zoospores, gametes, and zygospores. Key phyla include the Chlorophyta (green algae), Phaeophyta (brown algae), and Rhodophyta (red algae).
Unicellular green algae like Chlamydomonas reproduce through binary fission and flagellated zoospores. Algae are classified based on their photosynthetic pigments. Green algae contain chlorophyll a, chlorophyll b, and carotenoids. Spirogyra is a filamentous green alga with cylindrical cells arranged in helical filaments. It reproduces asexually through fragmentation and sexually through scalariform and lateral conjugation. Volvox is a colonial green alga. Red algae exhibit varied multicellular forms and contain the red pigment phycoerythrin.
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.
Similarities and dissimilarities of algae and plantsasifgondal37
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.
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.
3. Algae differ from plants, fungi, bacteria, and other organisms in their habitat, autotrophic

Brown algae include approximately 1500 species. They are multicellular, marine algae that range in form from simple filaments to large kelp. Brown algae obtain nutrients through photosynthesis and absorption. They reproduce asexually through spores produced in sporangia, and their lifecycle involves an alternation of generations between diploid and haploid phases. Brown algae are found in temperate and cold waters worldwide, inhabiting coastal intertidal and subtidal zones. They are economically important as food and sources of alginates and emulsifiers.

- The four main groups of land plants (bryophytes, pteridophytes, gymnosperms, and angiosperms) evolved from green algae called charophyceans and have adaptations for terrestrial living including multicellular embryos, vascular tissue, alternation of generations, and sporangia that produce spores.
- Charophyceans are the closest living relatives to land plants, sharing features like rosette cellulose complexes and peroxisomes.
- Key adaptations that enabled plants to colonize land include apical meristems, retention of embryos on the parent plant, alternation of generations between haploid gametophytes and diploid sporophytes, and the production of hardy sp
Algae are a diverse group of organisms that range from unicellular to multicellular forms. They are found in aquatic and terrestrial environments. Reproduction in algae can occur through vegetative, asexual, and sexual means. Vegetative reproduction is by fragmentation. Asexual reproduction is through spores like zoospores. Sexual reproduction involves fusion of gametes that can be isogamous, anisogamous, or oogamous. Algae are classified into three main groups - green algae, brown algae, and red algae - based on pigments and other characteristics.
The document summarizes key information about bacteria. It states that bacteria are prokaryotic single-celled organisms that do not have a nucleus and vary in size from 1 to 10 micrometers. It describes the main cellular structures of bacteria, including the plasma membrane, cell wall, cytoplasm, DNA, and flagellum. It notes that bacteria can be harmful when they cause diseases, but they can also be beneficial as they are used to make food and medicines, and are important decomposers.
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).
This document provides information on various kingdoms and types of organisms. It discusses key characteristics of Eubacteria, Protista, Fungi, Plantae, and Animalia kingdoms. Within these kingdoms, it describes important groups like cyanobacteria, mycoplasma, chrysophytes, dinoflagellates, euglenoids, slime moulds, protozoans, ascomycetes, basidiomycetes, and deuteromycetes. It also summarizes generalized life cycles of fungi and alternation of generations in plants.
- Cyanobacteria are a primitive group of blue-green algae that can be found in almost any environment. They are prokaryotic organisms that can exist as individual cells or form colonies.
- Cyanobacteria play an important ecological role in nutrient cycling and carbon fixation. Some cyanobacteria can fix atmospheric nitrogen. They are also used commercially for applications such as fertilizer production.
- Large scale cultivation of cyanobacteria is possible using photobioreactors like tubular reactors which maximize sunlight exposure while protecting the culture. Proper design of photobioreactors is important for scaling up cyanobacteria production.

It describes algae as simple, mostly aquatic photosynthetic organisms that can range in size from microscopic to massive. They reproduce both sexually and asexually. Algae are divided into green algae, brown algae, and red algae.
Bryophytes are described as the first plants to live on land but still requiring water for reproduction. They lack true roots, stems and leaves. Liverworts and mosses are the two divisions of bryophytes.
Pteridophytes are introduced as the first plants with vascular tissues
Protists are a diverse group of eukaryotic organisms that can be unicellular or multicellular, and include photosynthetic and heterotrophic species. They include algae, which are photosynthetic protists that can be single-celled or colonial, and diatoms and dinoflagellates, which are important marine algae with distinctive cell coverings or structures. Reproduction in algae can occur sexually through meiosis or asexually through cell division or fragmentation.
Algae are a diverse group of photosynthetic organisms that range in size from microscopic to 60 meters in length. They play important ecological roles as oxygen producers and as a food source. Algae are economically important as sources of biofuel, food, and pharmaceutical products. They can be isolated from soil or water samples and cultured using media such as F/2 or Beneck's broth. Growth is measured by cell counting or dry weight. Strains are selected based on traits like size, lipid content, and resistance to contamination. Large-scale cultivation can occur in open ponds or photobioreactors, with closed systems providing better control of growth conditions.
This document provides information on the structure and composition of algae. It begins by defining algae as chlorophyll-containing plants that lack true roots, stems, and leaves. It then discusses the different types of algal habitats, including aquatic, terrestrial, and unusual habitats. Various examples of algae from each habitat are provided, such as Cladophora and Chara from freshwater and Ectocarpus and Saragassum from marine environments. The document concludes by describing the different thallus structures found in algae, ranging from unicellular to colonial to filamentous and parenchymatous forms. Examples highlighting each structure type are cited.
This document provides an overview of seedless plants, including characteristics of green algae, mosses and bryophytes, and seedless vascular plants such as ferns. It describes how these plants reproduce without seeds, through spores and alternation of generations between haploid and diploid phases. It also explains how the evolution of vascular tissue in plants allowed for more efficient transport of water and nutrients, enabling some seedless plants like ferns to grow larger.
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...Joshua Orris
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.

Monitor indicators of genetic diversity from space using Earth Observation dataSpatial Genetics
Genetic diversity within and among populations is essential for species persistence. While targets and indicators for genetic diversity are captured in the Kunming-Montreal Global Biodiversity Framework, assessing genetic diversity across many species at national and regional scales remains challenging. Parties to the Convention on Biological Diversity (CBD) need accessible tools for reliable and efficient monitoring at relevant scales. Here, we describe how Earth Observation satellites (EO) make essential contributions to enable, accelerate, and improve genetic diversity monitoring and preservation. Specifically, we introduce a workflow integrating EO into existing genetic diversity monitoring strategies and present a set of examples where EO data is or can be integrated to improve assessment, monitoring, and conservation. We describe how available EO data can be integrated in innovative ways to support calculation of the genetic diversity indicators of the GBF monitoring framework and to inform management and monitoring decisions, especially in areas with limited research infrastructure or access. We also describe novel, integrative approaches to improve the indicators that can be implemented with the coming generation of EO data, and new capabilities that will provide unprecedented detail to characterize the changes to Earth’s surface and their implications for biodiversity, on a global scale.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
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.
