UNIT 9

4. the tightly packed photosynthetic cell found just under the epidermis in many leaves
9. A green pigment that absorbs light and captures light energy for the cell. Found in thylakoids, which are found in chloroplasts
10. in plants, the solution that surrounds the thylakoids in a chloroplast; site of light-independent reactions
11. top and bottom of a leaf, thin layer of cells that allow light to pass into the middle of the leaf
12. plants use the sun's energy to convert water and carbon dioxide into sugars

1. openings in leaves that regulate the movement of H2O, O2, and CO2
2. A stacked portion of the thylakoid membrane in the chloroplast. Grana function in the light reactions of photosynthesis
3. reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugars
5. located beneath the palisade cells also contain chloroplasts but more importantly they are the site of gas exchange
6. Living vascular tissue that carries sugar and organic substances throughout a plant
7. The two cells that flank the stomatal pore and regulate the opening and closing of the pore
8. An organelle found in plant and algae cells where photosynthesis occurs
