Across
- 3. vascular system conducts food material for storage
- 4. Site for the collection and evacuation of CO2
- 7. in palisade layer organelles for photosynthesis and producing glucose
- 9. carries/conducts water
- 10. single thickness cuboidal shaped cell layer. Covers and protects leaf. Like skin.
Down
- 1. opening allows gases (CO2 and O2) to exchange
- 2. regularly arranged cylindrical cells primary photosynthesis tissue
- 5. think wallled loose packed where gas exchange occurs
- 6. waxy layer prevents leaf from drying out. thickest in plants in arid regions.
- 8. two cells that protect stoma by opening and closing
