Across
- 1. the layer where most photosynthesis is done
- 4. hole that allows carbon dioxide and oxygen to enter and leave
- 5. the attraction between the Xylem walls and the water molecules
- 7. air space for exchange of gas within the leaf
- 9. The tension created that "pulls" water in the plant Xylem
- 10. the process that allows water to enter the root cells of a plant
- 11. transport system that carries water and sugar to the leaf
Down
- 2. excretion of water from the surface of cells in the leaves
- 3. the attraction between water molecules
- 6. these control the opening and closing of the stomata
- 8. the surface layer of the leaf that is transparent
