WHAT DOES GAMETOPHYTIC MEAN IN ENGLISH?
A gametophyte is the haploid multicellular stage in the alternation of generations during the life cycle of land plants and algae. It is produced from mitotic cell division of spores, which are produced by meiosis in sporophytes. Gametophytes produce haploid male or female gametes, by mitosis. The female and male gametes are also called, respectively, egg cells and sperm cells. The fusion of male and female gametes produces a diploid zygote, which develops by repeated mitotic cell divisions into a multicellular sporophyte. Because sporophytes are the product of the fusion of two haploid gametes, these sporophyte cells are normally diploid, containing two sets of chromosomes. The mature sporophyte produces spores by a process called meiosis, in which the chromosome pairs are separated once again to form single sets. The spores are therefore once again haploid and develop into haploid gametophytes. In bryophytes, the gametophyte is the dominant form and thus the most familiar phase of the life cycle. The sporophytes are attached to and dependent on the long-lived gametophytes. Moss gametophytes originate from the germination of a spore.
