Across
- 2. a subatomic particle with a negative electrical charge
- 4. The spongy,colorless matrix of a cell that functionally supports the cell.
- 8. the process by which green plants and certain other organisms transform light energy into chemical energy.
- 10. addition of carbon dioxide to organic molecules
- 12. microscopic openings in plant tissues that allow gas exchange
- 13. coenzyme that functions as a universal electron carrier, accepting electrons and hydrogen atoms to form NADPH

Down
- 1. Organisms that eat others for food
- 3. cycle of chemical reactions performed by plants to “fix” carbon from CO 2 into three-carbon sugars
- 5. a green pigment that helps plants, algae and cyanobacteria convert light energy into chemical bonds
- 6. the middle layer of leaf tissue that contains chloroplasts for photosynthesis
- 7. a process by which plants consume oxygen and release carbon dioxide during photosynthesis, resulting in a decrease in photosynthetic output
