Life Cycle Of Bryophytes at Life

Life Cycle Of Bryophytes. Like all land plants (embryophytes), bryophytes have life cycles with alternation of generations. Gametophytes produce haploid sperm and eggs which fuse to form diploid.

Spores germinate into gametophytes, the zygote develops into a sporophyte that releases spores, and then spores produce new gametophytes. The two phases are morphologically distinct. 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.

Bryophytes • plants without well developed vascular systems. A haploid gametophyte cell contains a fixed number of unpaired chromosomes. It gives rise to diploid sporophyte, which, however, contains twice the number of paired chromosomes. The antheridia (male) and archegonia (female).
