Across
- 3. the sticking together of similar molecules, such as one water molecule being attracted to another water molecule. It also causes water molecules to form drops.
- 5. the woody tissue which supports and transport water in vascular plants.
- 6. the loss of water by evaporation in terrestrial plants, especially through the stomata (accompanied by a corresponding water uptake from the roots).
- 10. Small pores in the underside of leaves that allow gases to diffuse in and out and water to leave the leaf
- 12. Plants that live in very salty conditions
- 14. the joining of two different substances due to attractive forces that hold them, such as keeping the water drops on the surfaces of leaves.
- 15. Water attracts to itself and other materials because it is.....
Down
- 1. 2 words. Water must be lost through leaves (it is inevitable) in order to allow for this process to take place, and for photosynthesis to occur
- 2. 2 words. the force created by evaporation of water coupled with the cohesive and adhesive forces in plants, enough to support a column of water against the forces of gravity in plants and trees.
- 4. 2 words. Increase the surface area for absorption of water by roots in some plants
- 5. A plant adapted to live in very dry conditions
- 7. a device used for measuring the rate of water uptake of a plant due to photosynthesis and transpiration.
- 8. The type of cell that creates the pore to allow gases and water vapour to exit a leaf
- 9. action of a tube of small internal diameter that pulls liquid up due to interactions of the liquid with the side and itself.
- 11. Factors that affect the rate of water loss such as temperature, humidity
- 13. net movement of water molecules through a semi-permeable membrane from an area of higher water potential to an area of lower water potential.
