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