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: 1.Herbaceous 2.Shrub 3.Vine 4.tree

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

10. Root tip

11. Types of roots: Tap root Fibrous root

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 tissues tissue= 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 Monocot seed Dicot 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
