D. Class. What are the general characters of bryophytes? Flagella with fibrillar hairs in one row. 2. Flagella roots consists of 4 cruciately arranged microtubular roots and some­times a rhizoplast. 9. It is the largest class of algae They are commonly known as green Algae. 3. Class. Plant body bilate­rally symmetrical. stream 1.1 ClASSIFICAtIon The classification of algae is complex and somewhat controversial, especially concerning the blue-green algae (Cyanobacteria), which are sometimes known as blue-green bacteria or Cyanophyta and sometimes included in the Chlorophyta. The nucleus is incipient type and lacks membrane bound organelles. Flagella inserted into the cell approximately parallel to each other. 9. 5. Division. 3. In addition, other pig­ments like chlorophyll a, β-carotene and c-phycoerythrin are also present. The reserve foods are cyanophycean starch and cyanophycean granules (pro­tein). Dictyochophyceae is divided into 3 orders: 1. Flagella are attached at anterior end of cell. 3. Phycobiliproteins occur inside the thylakoids of the choloroplasts. Group 1 consists of prokaryotic algae known as Cyanophyta or blue-green algae. 5. 1. %���� Lee, 1999, 3rd Edn.) Bold and Wynne’s Classification (1985) 5. Class. Yeast: Origin, Reproduction, Life Cycle and Growth Requirements | Industrial Microbiology, How is Bread Made Step by Step? 2. Multilayered structure (MLS) may be present, rhizoplast absent. It was Leeuwenhoek, 1674 who first observed unicellular algae under the microscope. Dinophysiales e.g., Dinophysis, Phalacroma. Dr. Poonam Jaiswal, Lecturer Botany, JDB Govt. Flagella inserted into the cell approximately parallel to each other. Presence of unilocular and plurilocular sporangia, chlorophylls a, c1 and c2, fucoxanthin; storage product chryso­laminarin found in vesicles in cyto­plasm; presence of anterior tinsel flagel­lum and posterior whiplash flagellum. Bangiales. According to R.E. Prochlorophyta (prochlorophytes). d. The dominant pigment is r-phycoerythrin (C34H46O8N4) which gives red colour to the algae. Zoospores are flagellated, one of which is tinsel type. red algae wikipedia. The anterior end of the cell has a large golgi apparatus, and sometimes con­tractile vacuole. Life cycle patterns. Eutreptiales. e. Sexual reproduction is rare and iso­gamous type only. “The Structure and Reproduction of the Algae” based on the following characteristics: ii. It takes place by cell divi­sion. 2. e.g., Cladophora, Chaetomorpha. Classification of Algae. Examples are Chlamydomonas, Spirogyra, and Chara Phaeophyceae – Also called as brown algae, they are predominantly marine. g. Sexual reproduction ranges from isogamy to oogamy. In telophase, the interzonal spindle collapses; phycoplast produces the new cross wall in cell division. e.g., Polysiphonia etc. e.g., Stichococcus, Raphidonema, Klebsormidium etc. 3. Where are the pollen grains formed in the flower? Bacillariophyceae is divided into 2 orders: 1. Pavlovales. The class Charophyceae is further divided into 4 orders: 1. Classification of Algae. Division. Sexual reproduction ranges from iso­gamy to oogamy. e. Flagella if present are equal in length and are situated anteriorly. 5. One membrane of chloroplast and endoplasmic reticulum. Alga is the singular of algae with a changing size from microscopic unicellular micro-algae (Chlorella and Diatoms) to large massive kelps that are usually a length extending in meters (200 feet) and then there's brown alga. c. Chromatophores have naked pyrenoid- like bodies. Corallinales. Cyanophyta (blue green algae). Crysophyceae (golden-brown algae). Chlorophyceae (flagella are attached at the anterior end of the cell). The chloroplasts shows various shape ie. This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. Algae Classification By Lee [PDF] [EPUB] Algae Classification By Lee [PDF] [EPUB] Simple habit to get algae classification by lee the incredible sticker album from experienced author Why not The artifice is very easy if you acquire the folder right here. The anterior end of the cell has a large golgi apparatus and sometimes contrac­tile vacuole. Amoeboid vegetative cells are mostly restricted in this group (and Xantho­phyceae). e.g., Batrachosper­mum. 1. The cells are surrounded by a rigid two- part box-like cell wall (upper part is epitheca and lower part is hypotheca) composed of silica called the frustule. algae wikipedia. (b) Chloro­plast surrounded by one membrane of chloro­plast endoplasmic reticulum (E.R.) 3. Cryptophyta (cryptophytes): nucleomorph present between inner and outer membrane of chloroplast endoplasmic reticulum; starch is formed in grains between inner membrane of chloroplast endoplasmic reticulum and chloroplast envelop; chlorophyll a and c; phycobilipro­teins; periplast is found inside plasma mem­brane. They are heterotrophic or autotrophic … A brief outline of the classification up to class (with characteristics) is given below: The prokaryotic algae have an outer plasma membrane enclosing protoplasm containing photosynthetic thyla­koids, 70S ribosomes and DNA fibrils not enclosed within a separate membrane. The class has been divided into three (3) orders: ii. Prymnesiophyta (haptophytes). The cell wall is composed of mucopeptide, along with carbohydrates, amino acids and fatty acids. What is its function? Plant body is unicellular and live in fresh water or in soil. Division. The cyanome cytoplasm took over the formation of the storage product. o cell wall composition and structure. Eukaryotic algae with chloroplast surrounded by two membranes of chloroplast endoplasmic reticulum. Algae exist in a variety of shapes and forms—single-celled algae may be spherical, rod-shaped, or spindle-shaped, while multicellular algae may appear as colonies, filaments or tubes. The class Chlorophyceae is further divided into 8 orders: 1. e.g., Fucus, Ascophyllum, Sargassum etc. Our mission is to provide an online platform to help students to share notes in Biology. Chlorophyceae (flagella are attached at the anterior end of the cell). 4 0 obj Chlorophyceae (Isokontae, green algae): a. 8. Sexual reproduction involves the forma­tion of a dominant zygote. Phycobiliproteins occur inside the thyla­koids of the choloroplasts. Prymnesiophyta (haptophytes): haptonema, chlorophyll a, c1 and c2, fuco- xanthin; two whiplash flagella; scales com­mon outside cell; storage product chryso­laminarin is found in vesicles in cytoplasm. c. Cells contain many discoid chro­matophores. g. Reproduction takes place by both vege­tative (cell division, fragmentation etc.) Pasteur (1 914) coined the terms Cyanelles to endosymbiotic BGA, Cyanone for host and Syncyanosis for the association. iv. Greeks called the “Phycos” for seaweeds. Xanthophyceae (Heterokontae, yellow green algae): a. Depending on the mode of nutrition they may be photosynthetic auto­trophs, photosynthetic symbionts or colourless heterotrophs. They vary from single-celled flagellates to simple colonial and filamentous forms. 4.

Zoospores are flagellated, one of which is tinsel type. Presence of chlorophyll a and phycobiliprotein, e.g., Anabaena, Gloeotrichia etc. 4. They are mostly unicellular flagellated algae.
