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.
A close-up of individuals cells within the colony, 2 flagella and red eyespot are visible. Volvox is a Chlorophyte, or green alga. It exists as a grand spherical colony. Each little alga within the colony bears two flagella, whip-like hairs.The individual alga are connected to each other by thin strands of cytoplasm that enable the whole colony to swim in a coordinated fashion. The individual alga also have small red eye spots.lthough the colony is bigger, the individual cells of Volvox globator are slightly smaller (4 micron) than the cells of Volvox aureus (5 to 8 micron). The cells of Volvox aureus are also a bit more egg-shaped. An easier way to determine the species is to look at the sexual reproduction of Volvox.
