Classification of plants

  1. 1. Classification of Plants
  2. 2. Plant Kingdom Flowering Plants Non-flowering Plants
  3. 3. Ferns Mosses 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
  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.  2 groups Gymnosperms Angiosperms ●  roots, stems, leaves ●  vascular tissues (transport) ●  flowers, fruits (contain seeds) Flowering Plants
  13. 13. Pine tree Gymnosperms
  14. 14. needle-shaped leaves
  15. 15. Male cones (in clusters) Female cones (scattered)
  16. 16. 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.
  17. 17. Angiosperms ● Highly developed ● Flowering Plants ● Seeds inside ovary 2 TYPES ● MONOCOTYLEDONS ● DICOTYLEDONS
  18. 18. Monocotyledons Parallel veins
  19. 19. Characteristics of Monocotyledons ●  one seed-leaf ● leaves have parallel veins ●  herbaceous plants ●  e.g. grass, maize
  20. 20. Dicotyledons Veins in network
  21. 21. Characteristics of Dicotyledons ●  two seed-leaves ●  leaves have veins in network ●  e.g. trees, sunflower, rose
  22. 22. 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 Angiosperms
