Content: In ferns, the sporophyte is the dominant generation, and it produces spores in sporangia that occur in clumps called sori that are found on the underside of the leaves. Spores grow into the gametophyte generation if they land in a suitable place. The gametes, eggs, and sperm are then formed by mitosis. Both the mosses and ferns are able to disperse by spores that are carried by the wind. The gametes, in both cases, also rely on the water so that the sperm can swim to the egg and fertilize it. The moss life cycle
Mosses are considered more primitive plants than ferns, but they do still have an alternation of generations with a diploid sporophyte that alternates with a haploid gametophyte. Mosses are in the Division Bryophyta and the gametophyte is the dominant stage of the life cycle. The morphology of a moss plant is a little different from that of more advanced plants. There are stem-like and leaf-like parts to the plant which is attached to the soil by a rhizoid which acts as a root. Together these structures form the gametophyte which is the haploid stage.
