  1. THE PLANT KINGDOM

  2. All plants: • Are Multicellular • Are Autotrophic – photosynthetic • Have cell walls with cellulose (that polysaccharide that we can’t digest – burp!) • Have chloroplasts in their cells.

  3. Basic plant Parts: • Leaves • Stems • Roots • Flowers • seeds

  4. Leaves • Main site of photosynthesis • Consist of: • Blade • Veins • Petiole

  5. Leaves can be simple or compound • Simple – have one blade • Compound - have many blades per leaf

  6. Veins in leaves • Pinnate • palmate

  7. stems • Support leaves and flowers • Transport water and nutrients within plant • May be used for storage (potato)

  8. Types of stems: • Herbaceous • Shrub • Vine • tree

  9. roots • Absorb water and minerals • Anchor plant • Some store food (carrot)

  10. Root tip

  11. Tap root Fibrous root Types of roots:

  12. Flower – reproductive organ • Produces male and female gametes • Provides structure for fertilization

  13. seeds • Reproductive structure containing stored food and plant embryo

  14. Dispersal adaptations • Wind • Water • animals

  15. fruit • Structure containing seeds

  16. Plants in the biosphere • Producers – base of the food chain. • Energy in plants is transferred to all other organisms when the plants get eaten

  17. Provide oxygen for aerobic organisms

  18. Provide shelter for many organisms

  19. Human uses: • Agriculture: 90% of the food you eat directly or indirectly comes from only 20 different kinds of cultivated plants: • Rice, corn, wheat, potatoes, etc.

  20. Medicines from plants

  21. industry

  22. Uses of cellulose

  23. Fossil fuels

  24. Problems caused by plants • Some are poisonous… • Weeds • Root damage………..

  25. Plant cells • Rigid cell wall of cellulose and other tough materials • Cells are connected to each other by shared cytoplasm • Large central vacuoles

  26. Plant tissuestissue= group of similar cells performing the same function • Dermal – protective, covering • Outermost layer • Protection – includes bark in trees • Some cells contain chloroplasts, so they perform photosynthesis

  27. Vascular tissue – transport or conduct materials around plant Xylem – water and minerals up phloem – food down

  28. Ground tissue – fundamental tissue – not vascular, dermal or meristematic ground tissue–

  29. Parts of a Flower carpel receptacle

  30. Pollination – transfer of pollen from anther to carpel • Self pollination……………. • Wind pollination………. • Insect/bird/bat pollination

  31. Fertilization • Occurs after pollination

  32. Seeds embryo Dicot seed Monocot seed embryo

  33. Seedling growth

  34. Classification of Plants

  35. Plant diversity Nonvascular plants: Bryophytes – mosses – no xylem or phloem

  36. Vascular plants – xylem and phloem • Nonseed vascular plants - Ferns – reproduce using spores

  37. Seed producing vascular plants • Gymnosperms • Naked seeds (oh my!) • Angiosperms- • flowers

  38. Length of life of a plant • Annual biennial perennial

  39. The end
