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...
The gametophyte is the dominant stage of the life cycle in mosses; the sporophyte develops on the body of a gametophyte, where it lives for a briefer time than the gametophyte's life span. In ferns, the sporophyte is dominant; the gametophyte is tiny and short-lived. Both mosses and ferns have swimming sperm that require moisture to reach an egg.
