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 one of the best-known chlorophytes and is the most developed in a series of genera that form spherical colonies.ale colonies release numerous microgametes, or sperm, while in female colonies single cells enlarge to become oogametes, or eggs.   Volvox is found in ponds and ditches, and even in shallow puddles.
