5.3): 1. Microcystis, Anabaena, Nostoc, Oscillatoria, Tolypothrix, and Spirulina are some examples of blue green algae while Chlamydomonas, Chlorella, Pediastrum, Netrium, Hydrodictyon, Acetabularia, Ulva and Spirogyra are some examples of green algae. 3. The well-established up-regulation of genes coding for protective proteins during drying of desiccation-tolerant taxa has been central to previous efforts to understand (and manipulate) desiccation tolerance. 1. One special characteristic of blue green algae is their ability to fix atmospheric nitrogen. However, blue green algae are prokaryotic bacteria while green algae are eukaryotic protists. It includes about 2000 species, mostly marine. The oospore, the fertilized female egg, has spirals on its surface that were imprinted by the spiraling protective cells that surrounded the oospore. The plant body is a thallus differentiated into holdfast, stipe and lamina (blade or frond). Therefore, both blue green algae and green algae are photosynthetic organisms. Furthermore, both types are photosynthetic organisms. ADVERTISEMENTS: F.E. Blue green algae and green algae are two groups that include photosynthetic organisms. Chlorophyll A & B 2. It is a large, informal grouping of algae having the primary photosynthetic pigments chlorophyll a and b, along with auxiliary pigments such as xanthophylls and beta carotene. 3. But there are still pretty diverse set of algae that come out of that. 2. Our mission is to provide an online platform to help students to share notes in Biology. Trending Questions.

Sexual reproduction is isogamous, anisogamous, and oogamous type. Chlorarachniophytes, which belong to the phylum Cercozoa, contain a small nucleomorph, which is a relict of the algae's nucleus. Her research interests include Bio-fertilizers, Plant-Microbe Interactions, Molecular Microbiology, Soil Fungi, and Fungal Ecology. 7.

Green algae exhibit a wide variety of thallus forms, ranging from single cells to filaments to parenchymatous thalli. 2. 3. Photoautotrophs possess photosynthetic pigments to carry out photosynthesis. A few species are free-floating e.g. Nutrition is photoautopophic, except some colourless & parasitic forms like Harveyella which live on other red algae. 4. Verder ziet men in deze groep dat de microtubuli van het spoellichaam gedurende de telofase (eindfase) van de celdeling zoals bij landplanten een fragmoplast vormen. Overview and Key Difference What is its function? Algae (singular: alga) are simple, plantlike organisms. Share Your PDF File Title: Blue Green algae: an overview 1 Blue Green algae an overview Monique DAmour Safe Environments Programme (Longueuil, Québec) and Michèle Giddings Water Quality Microbiology Division (Ottawa, Ontario) Health Canada 2 Federal-Provincial Roles and Responsibilities for Drinking Water Responsibilities divided among levels of government. Fucus (rockweed), Sargassum (gulf weed). What are Red Algae. The thallus of red algae may be unicellular (Porphyridium), filamentous (Batrachospermum, Polysiphonia), pseudofilamentous (Astocystis), parenchymatous (Porphyra), lace-like (Gelidium), ribbon-like (Chondrus) etc. Nonmotile unicellular and colonial green algae play an important role in the diversity of freshwater and terrestrial algae of North America. Land plants have advanced over the members of green algae along the line of folio wing adaptations: 1. Reproduction occurs asexually by fragmentation or by the production of spores that develop directly into new individuals, or sexually by the union of two gametes. About 133 genera are included in Chapter 7, and, using the light microscope, they are characterized by their cytomorphological features and their modes of reproduction. Moreover, they are photosynthetic organisms that possess chloroplasts and photosynthetic pigments such as chlorophyll a and b, carotene and xanthophylls. Fritschiella divides this way) Thus, this is the key difference between blue green algae and green algae. As of 2019, genetic data supports splitting the green algae into two major lineages: chlorophytes and streptophytes. When growing in shallow water, they appear green due to more chlorophyll. The green algae are a large, informal grouping of algae consisting of the Chlorophyta and Charophyta/Streptophyta, which are now placed in separate divisions, together with the more basal Mesostigmatophyceae, Chlorokybophyceae and Spirotaenia. Other species of green algae have a symbiotic relationship with other organisms. Few green algal species are present in marine water and moist soils. Algae are photosynthetic plants that vary in size and shape. Some blue green algae form symbiotic relationships with plant roots. Kind find the below picture which is mentioned down and kind fill in the blanks ? Side by Side Comparison – Blue Green Algae vs Green Algae in Tabular Form There are three major groups of photoautotrophs as plants, cyanobacteria (blue green algae) and algae (including green algae). Some reproduce asexually by spores. They appear brown due to large amount of brown coloured xanthophyll pigments called fucoxanthin (C40H56O6). 5. Food reserves are starch, some fats or oils like higher plants. Photosynthesis is the process shown by photoautotrophs. About 5000 species are known, mostly marine except a few fresh water forms (Batrachospermum). Hence, the red algae are the deepest growing algae in the seas where other photosynthetic forms cannot grow. 6. in Molecular and Applied Microbiology, and PhD in Applied Microbiology. These pigments absorb blue-green region of spectrum i.e. The members are multi-cellular; but may be unicellular, colonial or coenocytic. This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. 7. 2. Share Your Word File Green algae: Charophytae: Life cycle of Spirogyra, Zygnema, Desmids Enkele kenmerken van de Charofyten zijn de aanwezigheid van chlorofyl a en b, de afwezigheid van fycobiline, en het gebruik van zetmeel als reserveproduct. Examples: Spirogyra, Ulothrix, Caulerpa,VoIvox, Acetabularia, Chlorella etc. 5.2): 1. 1. In addition, some green algae form a symbiotic association with fungi and form lichens, which are ecologically important. What is a mushroom shaped gland? Blue green algae are a group of prokaryotic organisms. Chlamydomonas, Chlorella, Pediastrum, Netrium, Hydrodictyon, Acetabularia, Ulva and Spirogyra are several species of green algae. Archetypical Basal Green Alga. As the name suggests, they are blue green in color, ranging from single-celled organizations to colonial forms. Chlorophyceae (Green algae) (Fig. The key difference between blue green algae and green algae is that blue green algae are prokaryotic organisms that belong to Kingdom Monera while green algae are eukaryotic organisms that belong to Kingdom Protista.. Photosynthesis is the process shown by photoautotrophs. 8. The Charophyceae, as represented by the large stoneworts (order Charales), date from about 400 million years ago. Saved from arthitectural.com. 8. Moreover, their bodies can be spherical, filamentous or sheet-like colonies. isolated on white background stock photo 73308961 from Depositphotos collection of millions of premium high-resolution stock photos, vector images and illustrations. Photosynthetic lamina is annual while stipe is perennial. About 7000 species are known, mostly freshwater except a few (- 10%) marine forms. 4. Blue green algae include unicellular organisms as well as multicellular organisms. It is also effective as a remedy for arsenic poisoning. The antiquity of the green algae (Viridiplantae) has been hotly debated and is still controversial today. Based on the structural variations there are present different phyla or divisions of algae. Whereas, green algae are a group of eukaryotic organisms. TOS4. However, some protists contain plastids that are believed to be from other eukaryotes. 2. 1. Besides, both can build up symbiotic relationships with other organisms. This is also a difference between blue green algae and green algae.

Accordingly, there is a difference between blue green algae and green algae based on their cellular organization and other characteristics. 6. Green plants include all organisms commonly known as green algae and land plants, including liverworts, mosses, ferns and other nonseed plants, and seed plants. They are prokaryotic in cellular organizations that resemble bacteria.
