Oogamy is a type of anisogamy in which the gametes differ in size and shape.
The huge female gamete in oogamy is non-mobile, while the little male gamete is.
Oogamy is a common kind of anisogamy, which includes all animals and land plants.
Bryophyte:
Bryophytes are non-vascular plants found in shady and moist areas.
Sexual reproduction in bryophytes (mosses, hornworts, and liverworts) and tracheophytes (vascular plants) is oogamous.
It is a modification in which the sex cells, or gametes, are of two sorts, a larger nonmotile egg and a smaller motile sperm are involved in fertilization.
