Photosynthesis (CAMDEN)

3. Units of light energy from the sun that can power photosynthesis in plant cells
4. Organisms that cannot make their own food
7. A green pigment that is present in most plant cells that give plants their characteristics green color
8. A sugar made during photosynthesis
11. Organisms that are able to make their own food
14. Any source of usable power
17. When a substance changes into another substance
21. The process in which cells make ATP by breaking down organic compounds
22. liquid interior of chloroplast
23. An electric force linking atoms
24. The gas released by plants

1. An organelle where photosynthesis occurs
2. sugar is sent to the cells mitochondria to make this
3. A colored chemical compound that absorbs light producing color
5. Flattened membranes where light reactions occur
6. The process plants use to make their own food, which fuels all their activities
9. The major source of energy for cellular reactions
10. The light- independent reactions that produce sugar
12. Opening in leaf where gas exchange occurs
13. An accessory pigment either yellow or orange in the chloroplasts of plants
15. Splitting of water
16. A complex protein produced by cells that acts as a catalyst
18. A stack of dis-shaped thylakoids, where light-dependent reactions of photosynthesis occur
19. Gas needed for photosynthesis, taken in by leaves
20. A plant organelle that contains chlorophyll and other pigments
21. A chemical substance present at the start of a process
