The fern life cycle and moss life cycle are similar in that they have alternation between sporophyte and gametophyte stages and that both rely on layers of water so that their sperm can swim from one...
To better understand alternation of generations in nonvascular plants, study the moss life cycle in Figure 3. It depicts the life cycle of a moss and helps to distinguish the haploid and diploid stages. Note the prominent form of the moss, the gametophyte, which is haploid (1n). This is the plant body that is most often observed.
