This diploid zygote divides via mitosis to become a multicellular organism. It really is called the sporophyte, and at maturity, it asexually produces haploid spores.

Gametophytes create haploid gametes, which fuse to create a diploid organism, as well as alternation in between diploid and haploid starts all once more.
