Plant Tissues and Organs

3. Movement of sugar through the phloem is called -------------. (13)
5. Internal cells of the leaf which can be either palisade or spongy. (9)
8. Root hair cells have lots of these to release energy for active transport. (12)
10. The plant leaf has a lower and an ----- epidermis. (5)
11. Type of cell which absorbs water from the soil (4,4)
13. The phloem carry this from the leaves to other parts of the plant. (5)
14. tubes which carry dissolved sugars from teh leaves to the rest of the plant. (6)
17. Mesophyll layer which has cells crammed full of chloroplasts for photosynthesis. (8)
19. Mesophyll layer which has lots of air spaces for gas exchange. (6)
20. Small holes in the leaves which allow gas exchange to occur. (7)

1. Movement of water up the plant in the xylem is called -------------.(13)
2. tubes which carry water and minerals up the plant from the roots to the leaves. (5)
4. A waxy layer on top of the leaf which reduces water loss (7)
6. Small holes in the end plates of the phloem cell walls which allow sugar to move through. (12)
7. This material strengthens xylem cells and stops them from collapsing. (6)
9. Xylem cells are ------ to allow free flow of water. (6)
12. layer of tissue which forms the surface of the plant. (9)
15. The xylem carry this up the plant to the leaves. (5)
16. Type of tissue which is used for growth of new roots and leaves. (8)
18. Also taken up from the soil by the roots as well as water. (8)
