6. the most common plant cells
9. waxy substance called that is present on the walls of the endodermal cells
10. stalk that extends from stem to the base of the leaf
11. make and store other plant pigments
13. outer layer of cork cells that protect woody plants from damage
17. waxy layer known that covers the leaves of all plant species to reduce the rate of water loss from the leaf surface
18. region of continuous cell growth and cell division
20. and provides support
21. main root the grows vertically from which many smaller lateral roots arise

1. hair-like structures on the epidermal surface
2. control the opening and closing of stomata
3. membrane of the central vacuole
5. elongated cells with unevenly thickened walls that provide structural support
7. points of attachment for leaves, aerial roots, and flowers
8. travels the length of the leaf and branches to each side producing veins of vascular tissue
12. membrane-bound organelles with their own DNA
14. transports water and nutrients in a
15. arrangement of leaves on a stem
16. aerial stem modification that enables the plant to climb surfaces for support
19. cells have secondary cell walls that are thickened with deposits of lignin but many of them are dead at maturity
