Although most ferns reproduce using spores, one group evolved seeds although they were not ancestral to other seed plants. Fern leaves possess a highly branched vascular system. Some ferns in. have leaves that are 6-9 m long and probably the most complex leaves in the plant kingdom.nlike most algae, land plants have a multicellular jacket for protecting the reproductive cells. BRYOPHYTES: liverworts, hornworts, mosses; 23,000 modern species. Spores of bryophytic plants represent the first known land plants from the Middle Ordovician.
