(Botany) the diploid form of plants that have alternation of generations. It develops from a zygote and produces asexual spores. Compare gametophyte
spo•ro•phyte(ˈspɔr əˌfaɪt, ˈspoʊr-)
the form of a plant in the alternation of generations that produces asexual spores. Compare gametophyte.
spo`ro•phyt′ic (-ˈfɪt ɪk) adj.
In plants, fungi, and certain algae, the individual organism or generation of organisms that produces spores. A sporophyte is formed from the union of the nuclei of male and female reproductive cells, and each of its cells has two sets of chromosomes. In nonvascular plants, such as the mosses and liverworts, the sporophyte is a small plant or a part that grows on top of the gametophyte. In vascular plants, such as the ferns, grasses, conifers, and flowering plants, the sporophyte is the main form of the plant. Compare gametophyte.
