Bryophytes are an informal group consisting of three divisions of non-vascular land plants, the liverworts, hornworts and mosses.
Like all land plants, bryophytes have life cycles with alternation of generations.
In each cycle, a haploid gametophyte, each of whose cells contains a fixed number of unpaired chromosomes, alternates with a diploid sporophyte, whose cell contain two sets of paired chromosomes.
Gametophytes produce haploid sperm and eggs which fuse to form diploid zygotes that grow into sporophytes.
Sporophytes produce haploid spores by meiosis, that grow into gametophytes
