Life cycle of lycophytes
WebLife cycle. Horsetails, like other vascular plants, display an alternation of generations: an asexual phase, represented by a sporophyte (the horsetail plant), and a sexual phase, the gametophyte, an inconspicuous, delicate, green plant. Each year, many gametophytes are initiated from spores, but apparently very few produce sporophytes in nature. WebThe life cycle of gymnosperms (conifers) and angiosperms (flowering plants) is dominated by the sporophyte stage (the plant structure that you see is the sporophyte), with the gametophyte remaining attached to and dependent on …
