Across
- 1. materials made from living cells and tissue
- 3. the gas needed for photosynthesis
- 5. this underground tissue absorbs water and nutrients from the soil
- 6. the surface has a material which protects it from drying out
- 7. the waste product from photosynthesis we breathe
- 8. the 'upper' and 'lower' skin of a leaf which protects it
- 12. this area inside the leaf has a lot of air in it and does little photosynthesis
- 13. one of the requirements for photosynthesis, its wet
- 14. long hollow tubes which carry water and minerals through the body of the plant
Down
- 2. a hole in the leaf which allow gas to pass through
- 4. a green pigment in chloroplasts used for photosynthesis
- 5. special cells which increase the surface area of the root
- 9. this word means "light"
- 10. plants make this and animals eat it for energy
