  1. 1. Ch. 1 Lesson 3 How are plants classified?
  2. 3. How plants transport water:
  3. 4. 1. vascular plants <ul><li>system of tubes that connect leaves, stems & roots - moves water & nutrients </li></ul><ul><li>adds support - plants can get big </li></ul>
  4. 5. 1. vascular plants <ul><li>examples: </li></ul><ul><ul><li>grass </li></ul></ul><ul><ul><li>dandelions </li></ul></ul><ul><ul><li>celery </li></ul></ul>
  5. 6. vascular plants system of tubes that connect leaves, stems & roots - moves water & nutrients
  6. 7. 2. nonvascular plants <ul><li>do NOT have: </li></ul><ul><ul><li>system of tubes </li></ul></ul><ul><ul><li>true roots </li></ul></ul><ul><ul><li>stems </li></ul></ul><ul><ul><li>leaves </li></ul></ul>
  7. 8. Examples of nonvascular plants :
  8. 9. 1. mosses <ul><li>largest group of nonvascular plants </li></ul><ul><li>Reproduce by spores </li></ul>
  9. 10. 2. hornworts
  10. 11. 3. liverworts
  11. 12. How plants reproduce:
  12. 13. 1. flowering plants <ul><li>make seeds & flowers </li></ul>
  13. 14. 2. conifers <ul><li>make seeds but do not make flowers </li></ul><ul><li>grow 2 kinds of cones </li></ul>
  14. 15. 3. spores <ul><li>ferns & mosses </li></ul><ul><li>do not make seeds </li></ul>
  15. 16. Let's Review
  16. 17. Biologists sort plants by how they: <ul><li>transport water </li></ul><ul><li>2. reproduce </li></ul>

  22. 23. spores <ul><li>ferns & mosses reproduce by </li></ul>
  23. 24. vascular or nonvascular ? <ul><li>celery </li></ul>vascular
  24. 25. vascular or nonvascular ? nonvascular hornworts
  25. 26. vascular or nonvascular ? <ul><li>dandelion </li></ul>vascular
  26. 27. vascular or nonvascular ? nonvascular liverworts
