3. Root System Two types: Fibrous root system Tap root system

5. Root System Regardless of which types, roots anchor the plant and take in water and nutrients

6. Stems The stem supports other plant parts such as the leaves, flowers, and fruit

7. Stems Two basic types of above ground stems are woody and herbaceous

8. Stems Carry water up to the leaves Sugars are transported down to the roots

9. Leaves The leaf manufactures food for the plant by using light energy

10. Photosynthesis Plants use carbon dioxide to manufacture food for the plant and release oxygen necessary for animal life at the same time

12. Temperature Affects the process of photosynthesis

14. Temperature The best rate of photosynthesis occurs between 65 – 85 degrees F

15. Leaves Leaves are useful for identification of the plant

17. Leaves The leaf edge (margin), shape, and arrangement are all important in plant identification

19. Flower Seed develop in the female part of the flower (pistil) The pistil then enlarges and becomes the fruit

20. Pistil (Female) Stigma- Style Ovary

21. Stamen (male) Anther Filament

22. Petals Attract Insect to aid in pollination

23. Fruit Ovary matures into a fruit that surrounds the seed

24. Seeds Develop in the pistil

25. Seeds Seed coat – protect Endosperm – food Embryo- Baby plant
