PLANT BIOLOGY

7. The site of aerobic respiration, where energy (ATP) is released from glucose.
8. The jelly-like substance where most chemical reactions take place.
9. The control center of the cell that contains the genetic material (DNA).
10. A large central space filled with cell sap that helps maintain cell pressure.
12. Tissue that transports water and minerals up from the roots.
14. The rigid outer layer that provides structural support to the plant cell.
15. The organelle where photosynthesis actually takes place.
16. The lower mesophyll layer with air spaces to allow gas exchange.
17. The outermost layer of cells of the leaf.
18. A group of organs working together to perform complex functions.
20. The process of water loss from the leaf through the stomata.
22. The partially permeable layer that controls which substances enter and leave the cell.
23. The movement of water from the soil into the root hair cells.

1. The green pigment that absorbs light energy.
2. The simple sugar produced during photosynthesis.
3. The waxy, waterproof outer layer that reduces water loss.
4. The chemical process of using light to create glucose.
5. Pair of cells that control the opening and closing of the stomata.
6. A group of similar cells working together to perform a specific function, such as xylem or phloem.
11. Tissue that transports sugars produced by photosynthesis to the rest of the plant.
13. A structure made of different tissues working together, such as a leaf or a root.
18. Tiny pores, usually on the underside, that allow gases to enter and exit.
19. The upper layer of mesophyll cells packed with chloroplasts for photosynthesis.
21. The chemical solution used to test for the presence of starch in a leaf.
