  1. Kingdom Plantae Another of our kingdom survey Biology I / Mr. Fuentes

  2. Kingdom Plantae Plants dominate the land and many bodies of water. They exhibit tremendous diversity. Some are less that 1 mm to other as big as 100 m.

  3. Objectives • Name characteristics of plants • Summarize the classification of plants • Describe adaptations of plants to live on land

  4. Analyze this picture: (in groups) What do you see? What can you make of this picture?

  5. Analyze this picture: (in groups) What do you see? What can you make of this picture? Which organism do you think plants evolved from?

  6. Which plants are thought to be the first ones to appear on land? In what order they appeared?

  7. Characteristics of Plants

  8. Characteristics • Plants do all share some characteristics: • All plants are Photosynthetic. • All Plants are Multicellular. • All Plants are Eukaryotic Organisms..

  9. Adaptations of plants to live on land • From aquatic algae, aquatic plants to land plants. •     Cuticle to prevent water loss. •     Reproducing by spores and seeds. • Vascular tissue.

  10. Classification of plants

  11. Classification of plants

  12. Objectives • Distinguish between vascular and non vascular plants • Explain the advantages of seeds for reproduction on land • Distinguish between dicots and monocots

  13. Classification Non vascular Vascular Dispersal {spore (Single cell) vs. seed} Body an axis (stern) Large surface Many subdivision and classes Body structure Vascularization • Disperse by spores (seedless) • Not true roots, stems or leaves • Small • No vascular tissue • Grow in clumps or masses • Many capable of prolonged dehydration • Most lack cuticle (protective surface layer)

  14. Advantages of seeds for reproduction on land • Greater chance of reproduction success • Protection of the embryo

  15. Two main groups of seed plants Angiosperms Gymnosperms Seeds in fruit bodies Flowering plants • Naked seeds in cones

  16. Seeds Plants Angiosperms Gymnosperms

  17. Two groups of flowering plants Monocots Dicots Two cotyledons • One cotyledon

  18. Flowering Plants Monocots Dicots

  19. Classify these photos: non-vascular, vascular, spore, seed
