Photosynthesis

3. plant tissue that moves sugar down a plant from leaves to stem to root
4. photosynthetic organism that "produces" it's own food - means the same as autotroph
6. organ of the plant responsible for taking in water and nutrients from the soil
11. photosynthetic organisms in aquatic environments
13. microscopic holes through which plants "breathe" or exchange gasses - mostly located on the underside of the leaf
15. C6H12O6
16. process by which plants and plantlike organism use the sun's energy to produce sugar
18. plant tissue that moves water up a plant from roots to stems to leaves
19. areas of the plants where sugar is stored as simple sugars or starch
20. middle layer of the leaf where photosynthesis occurs - cells contain chloroplasts

1. raw materials, or reactants, needed for photosynthesis
2. products of photosynthesis
5. gas that exits the stomata of the leaf
7. by-product of photosynthesis
8. cell part, or organelle, responsible for the process of photosynthesis
9. green pigment found in certain plant cells that traps the sun's energy during the process of photosynthesis
10. pair of crescent shaped cells that open and close the stomata
12. main organ of photosynthesis in a plant
14. organism that has to "consume" or eat other organisms for energy
17. gas that enters the stomata of the leaf
21. ultimate source of energy for photosynthesis
