Gametophyte is a haploid multicellular organism that develops from a haploid spore that has one set of chromosomes. The gametophyte is the sexual phase in the life cycle of plants and algae.

In seed plants the male gametophyte is hidden in the pollen grain, and the female gametophyte is hidden in the ovule, after pollination and fertilization the ovule develops into the seed. Angiosperm and gymnosperm gametophytes and seeds are distinct.
