  5. Rhizoids • Anchor and absorb water

  6. Importance • Bogs • Very acidic • Peat • Fuel

  7. Liverworts • Look like human liver • Wort = old English for plant

  8. Hornworts • Horn structures grow out of gametophytes • Those are the sporophytes

  9. Seedless Vascular Plants

  10. Seedless Vascular Plants • No seeds • Vascular tissue • Types • Ferns • Club mosses • Horsetails

  11. Vascular tissue • Transport materials • Strong structure • Straws

  12. Reproduction • Grow by water • Release spores • Allows the sperm to swim to the egg

  13. Ferns • 12,000 different species

  14. Fern Structure • Stem, leaves, and roots • Stem is underground • Leaves grow on the top side • Roots on the bottom side
