Classification Of Plants

  1. 1. Classification of Plants
  2. 2. Plant Kingdom Flowering Plants Non-flowering Plants
  3. 3.  3 groups Ferns Mosses Gymnosperms Non - flowering Plants Do NOT produce flowers
  4. 4. A plant can be divided into 3 parts
  5. 5. Examples of Mosses
  6. 6. Moss spores Spore-producing capsule
  7. 7. Characteristics of Mosses  No true roots, No vascular tissues (no transport)  Simple stems & leaves  Have rhizoids for anchorage  Spores from capsules (wind-dispersal)  Damp terrestrial land  Simplest plants
  8. 8. Fern
  9. 9. Fern underground stem root A leaf (finely divided into small parts)
  10. 10. spore-producing organs (circinate) young leaf
  11. 11. Characteristics of Ferns  roots, feathery leaves & underground stems  have vascular tissues (transport & support)  Damp & shady places  Spore-producing organ on the underside of leaves (reproduction)
  12. 12. Pine tree Gymnosperms
  13. 13. needle-shaped leaves
  14. 14. Male cones (in clusters) Female cones (scattered)
  15. 15. Characteristics of Gymnosperms  roots, woody stems  needle-shaped leaves  tall evergreen trees  cones with reproductive structures  dry places  vascular tissues (transport)  naked seeds in female cones
  16. 16.  2 groups Monocotyledons Dicotyledons  roots, stems, leaves  vascular tissues (transport)  flowers, fruits (contain seeds) Flowering Plants
  17. 17. Monocotyledons Parallel veins
  18. 18. Characteristics of Monocotyledons  one seed-leaf <ul><li>leaves have parallel veins </li></ul> herbaceous plants  e.g. grass, maize
  19. 19. Dicotyledons Veins in network
  20. 20. Characteristics of Dicotyledons  two seed-leaves  leaves have veins in network  e.g. trees, sunflower, rose
  21. 21. Plant Classification Non-flowering Plants Flowering Spore-bearing Naked seeds No roots with roots Mosses Ferns Gymnosperms 1 seed-leaf 2 seed-leaves Monocots Dicots
