Across
  1. 4. Structural carbohydrate found in the cell wall that gives plant cells its shape and strength
  2. 6. Gas which plants require in order to carry out photosynthesis. Its concentration can become a limiting factor if in short supply.
  3. 8. A Limiting factor which may reduce rate of photosynthesis when low.
  4. 10. Cycle that takes place in the stroma of chloroplasts when carbon dioxide is fixed to form glucose (C6H12O6)
  5. 11. Chemical substance that is orange in colour but can turn blue/black in the presence of starch
  6. 13. Plant cell organelle that contains chlorophyll to trap light energy
  7. 14. Rate at which a reaction is at its maximum
Down
  1. 1. Storage carbohydrate which can be tested for using iodine
  2. 2. Factor that limits the rate of a reaction such as photosynthesis when it is in short supply.
  3. 3. This molecule is split in the first stage of photosynthesis.
  4. 5. Name of the first stage of photosynthesis when water is split. (Photolysis)
  5. 7. Gas released during photosynthesis that is a by- product of the splitting of water
  6. 9. Process by which plants convert light energy into chemical energy
  7. 12. Sugar produced during the second stage of photosynthesis. Formula (C6H12O6)
