From: GCIDE
- Gametophyte \Ga*me"to*phyte\, n. [Gamete + Gr. fyto`n plant.] (Bot.) In the alternation of generations in plants, that generation or phase which bears sex organs and produces gametes. In the lower plants, as the alg[ae], the gametophyte is the conspicuous part of the plant body; in mosses it is the so-called moss plant; in ferns it is reduced to a small, early perishing body; and in seed plants it is usually microscopic or rudimentary.
