spo·ro·phyte

(spôr′ə-fīt′)
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.
