The common mode of sexual reproduction in Chlamydomonas is

Explanation

Isogamy is a type of sexual reproduction in which the gametes are identical in size, shape, and structure.Oogamy is a type of sexual reproduction in which the gametes are different in size, shape, and structure, with the female gamete being larger and non-motile, and the male gamete being smaller and motile. Anisogamy is a type of sexual reproduction in which the gametes are different in size, but similar in shape and structure. Hologamy is a type of sexual reproduction in which the entire organisms fuse to form a zygote. Chlamydomonas is a type of green alga that reproduces sexually through isogamy. This means that the gametes that Chlamydomonas produces are identical in size, shape, and structure. The gametes are also motile, meaning that they can move on their own. When two gametes fuse, they form a zygote, which develops into a new Chlamydomonas cell. Therefore, the correct answer is Chlamydomonas.
