Across
- 4. thin outer layer of the leaf
- 5. transports dissolved sugars
- 9. sites of photosynthesis
- 10. two layers of cells between the upper and lower epidermis
- 12. facilitate gas exchange
- 13. water leaving the leaf through the stomata
- 14. layer of the mesophyll that allows for gas exchange
- 15. attraction of water molecules to molecules of other substances
- 16. uses sugar and oxygen to produce energy
Down
- 1. blister-like structures on bark and woody stems
- 2. the pulling of water up the xylem
- 3. transports water and dissolved minerals up the stem
- 5. uses carbon dioxide and water to produce sugar
- 6. regulate the size of the stoma opening
- 7. attraction of water molecules to other water molecules
- 8. Increase the surface area of the roots
- 11. layer of the mesophyll which contains chloroplasts
