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 [...]
In this article we will discuss about the classification of dictyotaceae. Family Dictyotaceae: Plants are of moderate to large size, simple or branched, the divisions growing from apical cells or marginal rows of apical cells, forming fan-like foliaceous, strap- shaped branching thalli, usually composed of cortical and medullary layers of cells. Sexual and asexual generations are distinct, the plants of [...]
In this article we will discuss about the classification of fucales. Family Fucaceae: Plants are dichotomous or pinnate strap-shaped simple or with costate branches, in some cases with piliferous cryptostomata, often with buoyant air bladders. Receptacular portions of the thallus terminate main branches or form stalked lateral branch- lets, heterogamous to oogamous. Each oogonium forms several eggs. Genus Fucus of [...]
