Across
  1. 3. site of proteinsynthesis
  2. 5. waterproofing
  3. 7. site of respiration more in active cells
  4. 8. controls entry and exit from the cell
  5. 9. controls opening of stomata
  6. 11. contain chlorophyll for photosynthesis
  7. 13. focuses light
  8. 16. site of chemical reactions
  9. 17. diffusion of carbon dioxide and water vapour
  10. 18. stores water and food as sap
  11. 19. collect light for photosynthesis
  12. 20. allow gases to pass into an out of the leaf
Down
  1. 1. the more of this the faster photosynthesis happens
  2. 2. keeps shape and support
  3. 4. the more of this gas the faster photosynthesis happens
  4. 6. loosely packed with lots of air spaces
  5. 10. holds deoxyribosnucleic acid
  6. 12. he higher this is the slower photosynthesis is
  7. 14. contain many chloroplasts
  8. 15. extra glucose to keep the plant alive at night
