Medical Definition of GAMETOPHYTE

: the individual or generation of a plant exhibiting alternation of generations that bears sex organs—compare sporophyte
ga·me·to·phyt·ic \-ˌmēt-ə-ˈfit-ik\ adjective


noun    (Concise Encyclopedia)

In certain plants, the sexual phase (or an individual representing the phase) in the alternation of generations. The alternate, nonsexual phase is the sporophyte. In the gametophyte phase, male and female organs (gametangia) develop and produce eggs and sperm (gametes), which unite in fertilization (syngamy). The fertilized egg (zygote) develops into the sporophyte, which produces numerous single-celled spores, which in turn develop directly into new gametes.
