A gametophyte can be either female (producing eggs), male (producing sperm) or hermaphrodite (monoicous, producing both eggs and sperm).The radiating arms of female gameteophores (left) protect archegonia that produce eggs.
Spores may come in different sizes (microspores and megaspores), but strictly speaking, spores and sporophytes are neither male nor female.
The alternate generation, the gametophyte, produces eggs and sperm.
Plants have a complex lifecycle involving alternation of generations.
One generation, the sporophyte, gives rise to the next generation via spores.
Dioicous gametophytes of the liverwort Marchantia polymorpha.In this species, gametes are produced on different plants on umbrella-shaped gametophores with different morphologies.
