This diploid zygote divides via mitosis to be a multicellular organism. It really is called the sporophyte, and at maturity, it asexually provides haploid spores. The haploid spores then germinate into multicellular organisms known as gametophytes. Gametophytes develop haploid gametes, which fuse to create a diploid organism, along with the alternation amongst diploid and haploid starts all once more.
