What are the reproductive cells of moss and ferns called?

The reproductive cells of mosses are called gametes, produced by gametophytes, which are the dominant life stage in mosses. In ferns, the reproductive cells are also gametes, formed by the gametophyte generation, but ferns have a more complex life cycle that includes both gametophytes and sporophytes. The sporophyte generation in ferns produces spores, which develop into gametophytes.
