The Chlorophyceae are one of the classes of green algae, distinguished mainly on the basis of ultrastructural morphology. However, because recent molecular phylogeny largely contradicts the traditional subordinal and familial classifications, no classification system has yet been established that describes the subdivision of Volvocales in a manner consistent with the phylogenetic relationships. Fučíková K, Lewis LA, Lewis PO. These divisions are based on the following factors: (a) Major photosynthetic pigments present (b) Form of stored food (c) Cell wall composition Botrydium.

Green algae are eukaryotes characterized by chlorophylls a and b as the major photosynthetic pigments (but colorless, heterotrophic taxa are also present [e.g., Polytoma, Polytomella, and Hyalogonium]), starch (α-1,4 and α-1,6 polymer of glucose) located within the chloroplast as the major storage product, and flagella of the whiplash (smooth) type (e.g., Bold and Wynne, 1985). (2001). Similar to pigmentation in algae, the distributional difference in reserved food is also in the classification of different algal groups.
