Plants have chlorophyll and an alternation of generations. They differ from the "green algae" in that the young sporophyte -- or diploid plant -- begins its development within the tissues of its parent gametophyte --or haploid plant. They also differ in that the sporophyte and gametophyte are heteromorphic, that is the two generations look and develop differently from each other. Plant Biology - CliffsNotes.
