WebIn the life cycle of bryophytes, gametophytes are the dominant stage and are generally larger than sporophytes. The sporophytes of mosses are made up of a foot, a seta, and a sporangium. The foot is embedded in the gametophyte and absorbs nutrients from it. The seta, or stalk, transports the nutrients to the sporangium, which produces spores.
