Pine gametophyte (outside) surrounding the embryo (inside). A gametophyte is the haploid multicellular stage in the alternation of generations life cycle of plants and algae. It develops from a spore by mitotic cell division. Spores are the products of meiosis in sporophytes.Gametophytes produce haploid gametes by mitosis.he fusion of male and female gametes produces a diploid zygote, which develops by repeated mitotic cell divisions into a multicellular sporophyte. In bryophytes (mosses, liverworts, and hornworts), the gametophyte represents the longer lived, nutritionally independent and more visible stage of the life cycle.
Ferns are seedless vascular plants. Instead of seeds, they grow from spores. Spores grow into gametophytes, which in ferns are very tiny and short-lived. The gametophytes release sperm to fertilize eggs, and fertilization happens right on top of the gametophyte.
