Across
  1. 3. — Gas released as a product of photosynthesis.
  2. 4. storage — Way plants keep extra sugar (often stored as starch for later use).
  3. 7. respiration — Process cells use to break down sugar for usable energy.
  4. 9. — Substances made at the end of a chemical reaction.
  5. 10. equation — A model that shows reactants and products using symbols and formulas.
  6. 12. — Tiny openings on leaves where gases move in and out.
  7. 13. — Sugar (food) made by plants during photosynthesis.
  8. 15. — Process plants use to make sugar using sunlight, water, and carbon dioxide.
Down
  1. 1. — Starting materials in a chemical reaction.
  2. 2. — Anything that has mass and takes up space (like water and carbon dioxide).
  3. 5. — Plant cell structure where photosynthesis happens.
  4. 6. — Reactant absorbed by roots and used in photosynthesis.
  5. 8. — Green pigment that absorbs light energy.
  6. 11. dioxide — Gas from the air plants take in to help make sugar.
  7. 12. — The energy source that powers photosynthesis.
  8. 14. — The ability to do work; in photosynthesis it comes from light.
