In plants, fungi, and certain algae, the individual organism or generation of organisms that produces reproductive cells (called gametes). Each cell of a gametophyte has only one set of chromosomes, just as its gametes do. In nonvascular plants, such as the mosses and liverworts, the gametophyte is the main plant form. In vascular plants, such as the ferns, grasses, conifers, and flowering plants, the gametophyte consists of only a few cells—the embryo sac and the pollen grain. Compare sporophyte.
