Description: Volvox is a green algae and the culmination of the volvocine line. It is a hollow sphere made up of a single layer of 500-60,000 biflagellate cells. The flagella beat so as to turn the volvox in circles and therefore propel the spheres in water. Volvox is also polar.
Volvox is a polyphyletic genus of chlorophyte green algae in the family Volvocaceae. It forms spherical colonies of up to 50,000 cells.They live in a variety of freshwater habitats, and were first reported by Antonie van Leeuwenhoek in 1700.Volvox diverged from unicellular ancestors approximately 200 million years ago.olvox is a genus of freshwater algae found in ponds and ditches, even in shallow puddles. According to Charles Joseph Chamberlain, The most favorable place to look for it is in the deeper ponds, lagoons, and ditches which receive an abundance of rain water.
