lee classification of algae

Phaeophyta (brown algae): unilocular and plurilocular sporangia, chlorophyll a, c1 and c2; fucoxanthin; sto­rage product chrysolaminarin is found in vesicles in cytoplasm; anterior tinsel flagel­lum and posterior whiplash flagellum. Name the types of nitrogenous bases present in the RNA. 5. iv. Privacy Policy3. Chlorophyll a and c2 are present in the chloroplasts, with peridinin and neo- peridinin being the main carotenoids. 1. The dominant pigments are fucoxanthin, diatoxanthin and diadinoxanthin. Photosynthetic organisms have chloro­plasts surrounded by one membrane of chloroplast endoplasmic reticulum, which is not continuous with the outer membrane of the nuclear envelop. %���� Ceramiales e.g., Delesseria, Phycodrys etc. Primitive green algae, some of which gave rise to other classes in the Chlorophyta. 2. 2. Prochlorophyta (prochloro- phytes): Chlorophyll a and b; no phyco­biliproteins. Phycobiliproteins occur inside the thylakoids of the choloroplasts. 9. i. Cryptomonadales e.g., Cryptomonas, Cyanomonas. b. Pigments. Dictyochophyceae (silicoflagellates): 2. Algae Classification By Lee algae and photosynthetic bacteria bi 431 531 5 credits. Peranemaceae e.g., Petalomonas, Anisonema. Asexual reproduction takes place by endospores, exospores, akinetes, nannospores etc. 6. The class Rhodophyceae is divided into 10 orders: 1. One photoreceptor as a swelling on the short flagellum. Since Linnaeus (1753) published “Species Plantarum” and classified algae. e.g., Melosira, Chaeto- ceros etc. Most live in fresh water, but some are found in marine and soil habitats. 4. Cryptonemiales e.g., Gloeopeltis, Dumontia. 2. 8. For example, some phycologists place the classes Bacillariophyceae, Phaeophyceae, and Xanthophyceae in the division Chromophyta, whereas others place each class in separate divisions: Bacillariophyta, Phaeophyta, and Xanthophyta. e.g., Ulvella, Coleo­chaete. Gigertinales. Cell wall is composed of cellulose along with alginic and fucinic acid.

Many algologists (phycologists) have proposed different classification … 1. b. Micro-algae have the capacity to reduce atmospheric CO2 levels, thus fixing the increasing percentage of CO2 in the atmosphere, responsible for the global pollution problem. Pyrenoid- like bodies are present in lower forms. Membrane-bound chromatophores are absent. His classification was based on such criteria as pigmentation, types of flagella, assimilatory products, thallus structure and methods of reproduction. Nemaliales. d. Pyrenoid-like bodies are present in some members. 1980 - Lee used fine structural aspects of organelles such as chloroplast, ER, flagellum, eyespot and nucleus to classify the algae into 6 divisions and 15 classes. 3. 1. 2. • Thus, Phycology or algology is the study of the algae (singular, alga). (Out of about 4,000 species, about 200 species are of fresh water). e. Flagella. Cells are eukaryotic and cell wall is composed of pectic substance. 5. The dominant pigments are xanthophylls — give red or brown colour. Ceramiales e.g., Polysiphonia, Ceramium. girls college, Kota Division. The phylum Rhodophyta has a single class Rhodophyceae. Cells have numerous discoid chromatophores without pyrenoid. e. The reserve food is cyanophycean starch and cyanophycean granule (pro­tein). Phragmoplast produces new cross-wall after cell division. Lee algae can be classified into 4 groups. Robert Edward Lee divided the algae based on evolution and formed 4 evolutionary groups of algae which are further divided into 15 phyta (=divisions): Prokaryotic algae (Cyanophyta) Eukaryotic algae-with chloroplast surrounded only by the two membranes of the chloroplast envelope (Glaucophyta, Rhodophyta and Chlorophyta) and (c) chloro­plast surrounded by two membranes of chloro­plast endoplasmic reticulum (E.R). Xanthophyceae (yellow green algae): Eyespot in chloroplast; chloro­phylls a and e; presence of anterior tinsel flagellum and posterior whiplash flagellum. Reserve food is laminarin (polysaccha­ride), manitol (alcohol) and fat. It is a group of unicellular flagellates, characterized by the possession of a haptonema between two smooth flagella. Classification of Algae. 2. The cells can be photosynthetic or colourless and heterotrophic. Plant body bilate­rally symmetrical. You habit isolated the photograph album soft files right here.

Chlorophyta (green algae). e. Most members are unicellular and motile with two flagella. Common genera: Sinura, Mallomonas, Tessellaria etc. However, since blue-green algae are prokaryotes, they are not currently included under algae (because all algae are classified as eukaryotic organisms). 4. The cyanome cytoplasm took over the formation of the storage product. Sexual reproduction involves the forma­tion of a dominant zygote. classification of algae oilgae oil from algae. with some modification of his earlier classification proposed in 1989 in his book “Phycology”. d. Reserve food is laminarin (polysaccha­ride), manitol (alcohol) and fats. 2. Chloroplasts contain chlorophyll a, β carotene with two major xanthophylls being violaxanthin and vaucheriaxan- thin. Cell wall composed of cellulose along with alginic and fucinic acid. 1. 5. It takes place by cell divi­sion. 4.

Desmomonadales e.g., Desmocapsa, Desmomastrix. The cells are bilaterally or radially sym­metrical. 2. Division. Zygnematales. e.g., Stichococcus, Raphidonema, Klebsormidium etc. Presence of chlorophyll a and phycobiliprotein, e.g., Anabaena, Gloeotrichia etc. vi. Ectocarpales. 4. Yeast: Origin, Reproduction, Life Cycle and Growth Requirements | Industrial Microbiology, How is Bread Made Step by Step? 2. Dr. Poonam Jaiswal, Lecturer Botany, JDB Govt. c. Cells contain many discoid chro­matophores. Cladophorales. (Out of about 4000 species, about 200 species are fresh water.). Eukaryotic algae with chloroplast surrounded by one membrane of chloroplast endoplasmic reticulum. Division-level classification, as with kingdom-level classification, is tenuous for algae. In course of evolution these two membranes became the chloroplast envelop. The chloroplast contains chlorophylls a, c1 and c2 with the major carotenoid being the golden-brown fucoxanthin. The main pigments are chlorophyll a and e, β-carotene and xanthophylls. The nucleus is mesokaryotic in nature. Scaly or naked flagellates with interzonal spindles are persistent during cytokinesis; primi­tive green algae, some of which gave rise to the other classes in the Chlorophyta. Just as humans move from one place to another using our legs, algae move from one … Chlorophyta (green algae): Chlorophyll a and b; storage product starch is found inside the chloroplast. iv. Rhodymeniaies e.g., Rhodymenia, Champia. 2. They have tentacles or rhizopodia on basically amoeboid vegetative cells. It was Leeuwenhoek, 1674 who first observed unicellular algae under the microscope. What is its function? Cutleriales. Sexual reproduction is absent. 5. Sexual reproduction ranges from iso­gamy to oogamy. 3. Siphonocladales. Chlorococcales. The class Chlorophyceae is further divided into 8 orders: 1. b. Pigments. Erythropeltidales. Presence of chlorophyll c1. 8. e.g., Eutreptia, Eutreptiella etc. Cell wall is pectic and silicified and ornamented variously. 2. 1. Motile cells asymmetrical, two flagella are attached in a lateral position of the cell. <> Myxophyceae (Cyanophyceae, blue green algae): b. Photosynthetic pigments: They possesses chlorophyll a, chlorophyll b and small amount of β-carotenoids. 2. 4. Chrysotrichaies e.g., Chrysoclonium. Presence of chlorophylls a and d, phy­cobiliproteins include r-phycocyanin, allophycocyanin, and three forms of phycoerythrins (b, r and c). iv. Division. b.

The main pigments are Chlorophyll a and e, β-carotene and xanthophylls. 4. Scaly or naked flagellates with inter­zonal spindles those are persistent during cytokinesis. B. Plant body is unicellular and live in fresh water or in soil. E. Reproduction Sexual reproduction may be iso-, aniso- and oogamous type. 7. 2. Charophyceae (flagella are attached in a lateral position of the cell). Prymnesiophyta (haptophytes) : Haptonema, chlorophylls a and c1 and cy fucoxanthin; two whiplash flagella; scales common outside cell; storage product chrysolaminarin, found in vesicles in cyto­plasm. 4. Phylum. e.g., Batrachosper­mum.
