Genus Spirogyra of Zygnemataceae: It is one of the common green algae occurring chiefly in ponds, pools, ditches, and similar other places. It prefers still, rather than [...]
The following points highlight the four families under which chaetophorales has been classified. The families are: 1. Chaetophoraceae 2. Coleochaetaceae 3. Trentepohliaceae 4. Pleurococcaceae. Family # 1. Chaetophoraceae: Chaetophoralean algae are heterotrichous in habit frequently bearing terminal or lateral hair-like projections. In their heterotrichy both the erect and prostrate portions of the plant may be well developed (e.g., Stigeoclonium) or [...]
In this article we will discuss about the general features and phylogenetic relationships of phaeophyta. General Features of Phaeophyta: The Phaeophyta or brown algae, in general, are restricted to the sea—the seaweeds, with a few exceptional fresh-water forms (species of Heribaudiella, Sphacelaria, Lithoderma, Pseudobodanella and Pleurocladia lacustris, A. Br.). Usually the marine members are abundant in cold-waters. But warm-water brown [...]
