Transpiration

2. The BUBBLE moves ____________ the plant
8. Can be opened and closed to add water from the RESERVOIR
9. These substances also move with water through the XYLEM
10. Increasing wind increases this.
12. Structure that helps prevent water loss
14. The process by which water vapour moves
16. As well as volume, this measurement is needed to calculate a rate of transpiration
17. You need to mention this in Crit B to show that you are gathering sufficient data
18. An increase in this factor will decrease the rate of reaction
19. This moves through the potometer
20. These open and close the pores in the underside of the leaf
22. Pores in the underside of the leaf
23. These cellls contain many chloroplasts. Most photosynthesis occurs here.
24. Equipment used to measure the rate of transpiration

1. Contains water, used to reset a potometer
3. This increases the rate of transpiration as more stomata open
4. When water turns from a liquid to a gas
5. Water mainly evaporates from the surface of these cells
6. The use of control variables makes an experiment a ___________________
7. Increasing the temperature increases the rate of transpiration because of this
11. The process by which water moves in and out of cells
13. Structures through which water moves in a plant
15. Stomata open to allow the movement of this gas into a leaf
21. CONCGRADIENT is also affected by ________
22. The glass tube has this etched onto it/next to it
