<P> The horn - shaped sporophyte grows from an archegonium embedded deep in the gametophyte . The sporophyte of a hornwort is unusual in that it grows from a meristem near its base , instead of from its tip the way other plants do . Unlike liverworts , most hornworts have true stomata on their sporophyte as mosses do . The exceptions are the genera Notothylas and Megaceros , which do not have stomata . The sporophyte of most hornworts are also photosynthetic , which is not the case with liverworts . </P>
