Chrysophyaceae an Important Class of the Heterokontophyta

Teena Agarwal*

Algae are the heterogeneous group of organisms, they exert the profound kinds of the effects on the ecosystem, as they harbour the very big amount of the oceanic ecosystem, they produce the very large amount of the atmospheric oxygen and produces the tremendous amount of the organic carbon in the ecosystem. Much of the organic carbon works as the food into the biogeochemical cycles and the food chains. Algae produce a large amount of the secondary metabolites and they are used for the variety of the purposes. In this review articles we are presenting some of the aspects of the class chyrosphycaeae of the algae. Most of the species of the chrysophyaceae are the unicellular and the colonial, which may or may not be flagellates, the flagella are not inserted near the lateral side but at the apex of the cells. The chloroplast is the golden brown and the colour of the chloroplast are covered by the accessory pigment Fucoxanthin.

The chrysophyaceae are restricted to the fresh water habitats. These species have the haplontic kinds of the life cycles, the zygote of the cells are the resting stage and they are of the siliceous kinds. This class is best known for the planktonic kinds of the representatives. Then name of the class is due to the colour golden brown due to the presence of the accessory pigments due to which the green colours is masked by these kinds of the pigments. The members of the class are the primary producers and they play an important variety of roles in aquatic ecosystem.
