Algae range from single-celled organisms to multi-cellular organisms, some with fairly complex differentiated form. Algae Classification. F.E. Fritsch (1935) classified the whole of the algae into eleven classes on the basis of type of pigments, nature of reserve food material, mode of reproduction etc. Yellow-green algae or the Xanthophyceae (xanthophytes) are an important group of heterokont algae. Fritsch proposed a classification for algae­ based on pigmentation, types of ­flagella, ­reserve food materials, thallus­ structure and ­reproduction. Join now. Ø Distribution pattern of pigments has great taxonomic significance in algae. It is in the order Ceramiales and family Rhodomelaceae. Fritsch FE (1935) The structure and reproduction of algae, vol I.

Class-Dinophyceae (paridinieae) 7. Xanthophyte chloroplasts contain the photosynthetic pigments chlorophyll a, chlorophyll c, β-carotene, and the carotenoid diadinoxanthin. Ø Different groups of algae have different pigment composition. 3. Ø The classification of algae by Fritsch is primarily based of the pigmentation in algae. In many protocols, diatoms are identi- fied as alive (having plastids evident in frustules) or dead (Moulton et al. Fritsch’s Classification (1935) 2. Classification by F.E FRITSCH.
