Definition
The genus *Volvox* consists of colonial green algae, forming spherical or ellipsoidal colonies readily visible to the naked eye. These colonies are composed of numerous individual cells, each with flagella that beat in coordination to propel the colony through the water. Genus *Volvox* algae inhabit freshwater environments like ponds, ditches, and lakes. They serve as model organisms for studying the evolution of multicellularity, offering insights into cell specialization and cooperation. Consider them tiny, floating ecosystems. They are free-swimming and contribute to the balance of their freshwater environments.
