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.
The flagellate, Euglena, is often associated with these forms.. Volvox is a genus of chlorophytes, a type of green algae. 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 developed its colonial lifestyle 200 million years ago.ach mature Volvox colony is composed of numerous flagellate cells similar to Chlamydomonas, up to 50,000 in total, and embedded in the surface of a hollow sphere or coenobium containing an extracellular matrix made of a gelatinous glycoprotein.
