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 several multicellular protists. This is kelp, a multicellular algae: Mycoprotists, or fungus-like protists, have characteristics of fungus cells. Examples: Water molds, which are unicellular, and cellular slime molds, which are unicellular and multicellular at different stages of their life cycle. few are multicellular. What sets these multicellular protists apart from plants, animals and fungi is the fact that their cells are not specialized to perform specific functions. While protists can be divided into a variety of kingdoms, it is helpful to think of them as falling into several general groups.
