Sporophyte stage definition
WebThe diploid sporophyte is the most conspicuous stage of the life cycle. On the underside of its mature fronds, sori (singular, sorus) form as small clusters where sporangia develop. Sporangia in a sorus produce spores by meiosis and release them into the air. Those that land on a suitable substrate germinate and form a heart-shaped gametophyte ... Web7 Mar 2024 · A gametophyte is one of the two main stages in plants and algae that have alternation of generations.
