Definition
Glossary of "Life (9th ed.)" by Sadava et al. (2011)
- In plants and photosynthetic protists with alternation of generations, the multicellular haploid phase that produces the gametes. (Contrast with sporophyte.)
Glossary of "Plant Systematics (1st ed.)" by Simpson (2006)
- The haploid phase in the life cycle of all land plants.
Glossary of "Evolution of Plants (2nd ed.)" by Willis & McElwain (2014)
- The gamete-producing generation in the life cycle of a plant, i.e. the embryo sac in angiosperms and the prothallus in ferns.
Glossary of "A Botanist's Vocabulary" by Pell & Angell (2016)
- Life cycle generation in which a plant has one set of chromosomes (i.e., is haploid, 1n) and produces gametes (sperm or eggs); in seed plants the gametophyte is the ovule and the pollen grain; the gametophyte is dominant in both time and size for non-vascular plants, making it their most conspicuous generation, as with mosses.
- Antonym: sporophyte.
