Plant Structures

1. main root the grows vertically from which many smaller lateral roots arise
3. aerial stem modification that enables the plant to climb surfaces for support
4. membrane-bound organelles with their own DNA
5. transports water and nutrients in a
6. the ground tissue towards the interior of the vascular tissue in a stem or root
7. hair-like structures on the epidermal surface
8. points of attachment for leaves, aerial roots, and flowers
10. waxy layer known that covers the leaves of all plant species to reduce the rate of water loss from the leaf surface
11. outer layer of cork cells that protect woody plants from damage
13. arrangement of leaves on a stem
15. elongated cells with unevenly thickened walls that provide structural support
16. cells have secondary cell walls that are thickened with deposits of lignin but many of them are dead at maturity
17. waxy substance called that is present on the walls of the endodermal cells

1. membrane of the central vacuole
2. region of continuous cell growth and cell division
4. and provides support
6. the most common plant cells
9. control the opening and closing of stomata
10. make and store other plant pigments
12. stalk that extends from stem to the base of the leaf
14. travels the length of the leaf and branches to each side producing veins of vascular tissue
