  3. Cladogram for plants

  4. What adaptations allowed plants to come on to land? • Pollen grain • Cuticle • Stomata • mycorrhizae • Vascular tissue Xylem phloem

  5. Diversity of Plants

  6. BryophytesMoss, liverworts, hornworts • First land plants • No true roots, stems, or leaves • Contain no vascular tissue • Rhizoids instead of roots • Gametophyte is the dominant generation • Require water for reproduction

  7. FernsSpore Bearing Plants • Contains vascular tissue • Evolved 350 million years ago • Live in moist, acidic environments • Created coal deposits • Sporophyte dominant generation

  8. Anatomy of a Fern Fiddlehead a baby frond

  9. Gymnospermsconifers, cycads, ginkgos • Most ancient of the seed plants • Seeds lack protective outer coating

  10. Conifers- evergreens • Live in sandy soil, in a cool moist environment • Roots spread out over a large shallow area • Needlelike leaves covered with a thick waxy cuticle
