Across
  1. 4. Sugars and amino acids are transported around a plant in this
  2. 5. The layer of a leaf where most photosynthesis occurs
  3. 10. When plant cells contain a lot of water, they are said to be _______.
  4. 11. The process by which water changes state from a liquid to a gas on the surface of spongy mesophyll cells
  5. 12. A layer of cells on the top and the underside of plant leaves
  6. 13. To measure the rate of transpiration in a POTMOETER, you need to measure the distance moved by a bubble and the _______ this takes.
  7. 14. Pores in the underside of a plant leaf
  8. 16. The loss of water vapour from plant leaves
  9. 17. Hydrogencarbonate indicator will turn this colour in a test tube with a plant and an animal that is in the light
  10. 18. The process by which water enters and exits plant cells
  11. 20. A product of photosynthesis
  12. 21. The process by which mineral ions are absorbed in roots
Down
  1. 1. Xylem is made of long, _______, dead cells
  2. 2. These open and close STOMATA
  3. 3. This reaction happens constantly in plants (day and night)
  4. 5. A device used to measure the rate of transpiration
  5. 6. This gas diffuses into a plant during the daytime
  6. 7. Hydrogencarbonate indicator will turn this colour in a test tube with a plant that is in the light
  7. 8. STOMATA close to prevent this
  8. 9. An increase in this factor will decrease the water uptake of a plant
  9. 13. A feature of leaves that helps to increase the rate of diffusion
  10. 15. This is transported in the xylem
  11. 19. This ion/mineral is required for plants to make chlorophyll
