WebbThe foot is embedded in the gametophyte and absorbs nutrients from it. The seta, or stalk, transports the nutrients to the sporangium, which produces spores. Rhizoids, which resemble the roots of vascular plants, anchor the gametophytes to a substrate. Rhizoids are not vascular structures. Part B - Life cycle of mosses Webbdevelops into a sporophytic structure differentiated into foot, seta and capsule. Spores produced in a capsule germinate to form free-living gametophyte. PTERIDOPHYTES : • Main plant body is sporophyte which is differentiated into true stem and leaves. • Leaves may be small (microsporophyll) as in Selaginella or large (macrophyll) as in ferns.
