Across
- 7. plants use glucose for this
- 8. where gas exchange takes place
- 9. when water is lost from the leaves by evcaporation through the stomata
- 11. protective layer on top of the leaf, waterproof
- 12. absorbs and loses water to open and close the stomata
- 14. makes the roots go down and shoots go up
- 15. gas release by plant which controls fruit ripening
- 16. transports water
- 17. seeds germination hormone
- 18. - plant grows towards light
- 19. this and oxygen are products of photosynthesis
- 20. acts as a barrier for plants
Down
- 1. when soluble products of photosynthesis are transported around the plant
- 2. contains guard cells and stomata
- 3. cause of stunted growth
- 4. layer of the leaf which is tightly packed with chloroplasts to absorb light and photosynthesise.
- 5. make the plant unpleasant to eat
- 6. hormone controls growth
- 10. transports substances produced by photosynthesis around the plan
- 13. thin and transparent layer which allows light to enter the palisade layer underneath it
