What do the moss life cycle and the fern life cycle have in common

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 gametophyte to the eggs of another. This means that both ferns and mosses require relatively moist environments. They are also similar in that their gametophyte stage, unlike other plants, does not rely on sporophytes.
