Like other land plants, bryophytes exhibit alternation of generations, alternating between haploid and diploid phases, also referred to as diplohaplontic. Unlike other land plants, the dominant phase of bryophytes is the gametophyte. The sporophyte remains attached to and dependent on the gametophyte for water and nutrient throughout its life. Some species are dioecious (with female gametophytes and male gametophytes); other are monoecious (with bisexual gametophytes).
