Across
  1. 2. Process where plants make their own food
  2. 5. Lot of this is gotten from aerobic respiration
  3. 7. Substances formed in a chemical reaction
  4. 8. Source of food needed for respiration
  5. 11. Release of energy from food
  6. 12. Release of energy from food using oxygen
  7. 13. Small openings in the leaf that allow gases in and out
  8. 15. Where photosynthesis takes place in the cell
  9. 18. Release of energy from food without oxygen
  10. 19. Chemical reactions that happen in the cells of living things
  11. 21. Gas needed for respiration
  12. 22. This forms in muscle cells during anaerobic respiration
Down
  1. 1. Green pigment that absorbs light energy
  2. 3. All chemical reactions are controlled by these chemicals that help speed up reactions
  3. 4. Where respiration takes place in the cell
  4. 6. Another waste product of respiration
  5. 9. Gas released during repsiration
  6. 10. A factor that affects the rate of respiration. For example the enzymes in our body works best at 37 degrees Celsius.
  7. 14. Substances that combine together in a chemical reaction.
  8. 16. Organ that takes in and releases gases during respiration
  9. 17. This is formed during anaerobic respiration in yeast
  10. 20. Supplies light energy for photosynthesis
