Volvox, a type of green alga that forms spherical colonies and has unique features such as eyespots and flagella. Learn about their ecology, Volvox is a polyphyletic genus of chlorophyte green algae that form colonies of up to 50,000 cells. Learn about its history, description, reproduction, and colony inversion, and see its phylogenetic classification and synonyms. Occurrence of Volvox: Volvox is free floating fresh water green algae. Volvox grows as planktons on surface of water bodies like temporary and permanent ponds, lakes and water tanks. During rainy season due to its fast growth the surface of water bodies become green.
