Fritsch’s Classification of Algae: F.E. TOS4. of  the  Algae”(1935). In Xanthophyceae pectic substance is more common. is the unicellular form. Algae can have different types of photosynthetic pigments that allow them to photosynthesize at various depths in water. Latin ‘alga’ means seaweed. What are the general characters of bryophytes? Cyanophyceae or blue green algae are prokaryotic in nature whereas all other classes of algae are eukaryotic. A golden brown pigment called fucoxanthin is present and it There are different types of algal classification based on their characteristic. develops into carpospores. present. On the basis of nuclear organization algae can be prokaryotic or eukaryotic. We classify algae mainly by their molecular composition, for example the pigments they use for photosynthesis and the compounds they use for cell walls. Chlorophyll c is found in Phaeophyceae and Cryptophyceae. Alternation of generation is present. gives shades of colour from olive green to brown to the algal members of this 85 much stretch of imagination be considered reconstructed stem-forms, which inhabited Greater New Zealand or elsewhere during the earlier Pliocene or earlier still. The algae belong to the subphylum Thallophyta of the kingdom Protista in modern classification of organisms. In Prasinophyceae, prasionate type flagella are found. 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. Classification of Algae Taxonomic classification of algae is based upon the same rules that are used for the classification of land plants. from chlorophyll a, r-phycoerythrin and r-phycocyanin are the photosynthetic Classified algae into 7 divisions and divisions into different classes on the basis of :-  Physiology of vegetative cells.

Good examples of algae include seaweed, giant kelp, and pond scum. Different groups of algae have different types of pigments and organization of thylakoids in chloroplast. There aretwo types of algaeare classified into two different categories 1. Name the types of nitrogenous bases present in the RNA. Various systems of classification of the Phaeophyceae based on these morphological grounds have been proposed (SeeTable 5in Reviers and Rousseau, 1999). Rhodophy-ceae, Cyanophyceae (Table 2.2). The reproduction is oogamous and life cycles are usually complex in Rhodophyceae and Phaeophyceae. Criteria # 2. 1.A-D). Porphyridium reproduction is Oogamous. Members of this group include ‘Red algae’ and are mostly marine. Our mission is to provide an online platform to help students to share notes in Biology. The pigment is one of the most important criteria used in differentiation of classes in algae, as algae were initially and primarily separated on the basis of colour e.g., green algae, red algae, brown algae or blue-green algae. The carotenoids are of two kinds: Carotenes and Xanthophyll’s. Algae possess the usual … diplontic). Variation among the shape of the chloroplast is found in members of algae.

Motile The spermatium is carried gives shades of colour from olive green to brown to the algal members of this In Chlorophyceae the reproduction can be isogamous, anisogamous and oogamous, the life cycle can be simple or complex. He published his classification in the book “ The structure and reproduction of the Algae ”(1935). Eukaryotic algae have well differentiated nucleus, mitochondria, chloroplast and endoplasmic reticulum in their cell structure. Chlorophyll e is confined to Tribonema of Xanthophyceae. Algae exist in environments ranging from oceans, rivers, and lakes to ponds, brackish waters, and even snow. Many algologists (phycologists) have proposed different classification systems based on various algal characters. Chlorophyceae (Green algae) General characterstics of Chlorophyceae. ­Oogamous. Of course, it is thought that all plants developed from cyanobacteria (aka blue green algae). classification of algae was given by F.E Fritsch (1935) in his book ‘The Structure and Reproduction of the Algae’. pigments. The classification of algae has proved to be a complex process that has experienced several revisions over the years. In all other classes the basic flagellar structure is similar. The zygote In Rhodophyceae the cell wall is made of non-cellulosic polysaccharides like xylans and galactans. The chlorophylls in algae are chlorophyll a, b, c, d and e types. Share Your PPT File.
