Aphanochaete, Pandorina, etc. Oogamy: In oogamy a "large motionless female
cell or ovum is fertilized by a much smaller active male cell or spermatozoid" (
Fritsch, 1935).
A flagellated male gamete swims to the nonmotile egg cell and fertilization occurs
. This type of heterogamy is termed oogamy. Volvox, a colonial genus, has an
oogamous sexual reproductive life cycle, and also shows cellular specialization.

Broadly speaking, there are three general characters derived from modes of
sexual reproduction: oogamy, anisogamy, isogamy (we acknowledge that the
