This diploid zygote divides by way of mitosis to become a multicellular organism. It is called the sporophyte, and at maturity, it asexually produces haploid spores. The haploid spores then germinate into multicellular organisms called gametophytes. Gametophytes develop haploid gametes, which fuse to generate a diploid organism, as well as alternation amongst diploid and haploid starts all yet again.
