2. SCIENCE 7 TOPIC SIX

3. THE THREE FUNCTIONS OF ROOTS

4. 1. Anchor the plant in the ground

5. 2. Absorb water and minerals from the ground

6. 3. Store plant’s nutrients

7. XYLEM AND PHLOEM DIFFERENCES

8. Xylem is for upward movement of materials Phloem is for downward movement of materials

9. IMPORTANCE OF ROOT HAIRS

10. Root hairs greatly increase the surface area of the roots of a plant so it can absorb more nutrients

11. THE FUNCTIONS OF THE STEM

12. Support of the plant

13. Transport nutrients though the plant

14. Help hold leaves up toward the light

15. Store some of the plants nutients

16. HERB AND WOODY STEM DIFFERENCES……

17. Woody stems are found mostly as perennials

18. Herb stems are found mostly as annuals

19. Woody stems have a cambium layer that separates the xylem from the phloem

20. Herb stems have their xylem and phloem tubes grouped together

21. Woody stems are not pliable

22. Herb stems are pliable

23. THREE TYPES OF ROOTS

24. 1. Fibrous Root

25. 2. Tap Root

26. 3. Above Ground Root

27. Aireal
