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 can reproduce through asexual or sexual reproduction. Earlier, you read that some cells are specialized. There are a limited number of cells in the volvox that are dedicated to reproduction. Some of these cells can be male and other can be female.
