* All Algaes are Autotrophs * The Alga are called the Thallus because of lack of Vascular Tissue * All Algaes are Eukaryotic, Except Blue Green Algae (Prokaryotic) * The Biggest Single Cell Algae -Acetabularia, Used to Cytological Study * Some Single Cell Alga - Chlamydomonas, Chlorella, Euglena * Some Single Cell Thallus Structure Algae - Ulothrix, Spirogyra, Oedogonium * Some Branched Thallus Algae - Cladophora, Pithophora, Bulbochaete * False Branching Found in Scytonema * Some Heterotrichous Thallus Alga - stigeoclonium, Fritschiella, coleochaete, Bulbochaete * Some Epiphyte Alga - Oedogonium, Cladophora, Vaucheria * Parasitic Alga - Cephaleuros, Rodochytrium, Phyllosiphon, Harviyella - Cephaleuros Virescens - Affected Tea Leaf - Cephaleuros Coffee - Affected Coffee Leaf * Zoochlorellae is a Endozoic Algae - Growing inside the Hydra * Algae With root, stem Structure - Caulerpa, Sargassum, Laminaria, Fu
* Algae - Greek Word * Thallophytes are biggest division of cryptogams * Thallophytes - Algae, Fungi, Lichen, Virus and Bacteria * Unger was the first to use the term Thallophyte * The Study of algae is called Algalogy or Phycology * The term algae was first used by Linnaeus (1754) * Father of Algalogy - G.Klebs * Father of Modern Algalogy - M.O.P.Iyangar * Some Indian Algalogist from Tamil Nadu - V.Krishnamoorthy, M.O.P.Iyangar, T.V.Devakachari, V.Sundralingam * Fritsch (1935) classified the whole of the algae into 11 classes on the basis Types of Pigments, Nature of the Reserve Food Material, Mode of Reproduction, etc.... * Eleven classes there are, 1.Chlorophyceae, 2.xanthophyceae, 3.chrysophyceae, 4.Bacillariophyceae, 5.cryptoph
