Across
- 5. root which grows from the base of the stem
- 6. region of cells capable of cell division
- 12. leaves are attached to the stem by this
- 13. in this zone, cells develop into different types of tissue cells
- 14. long, narrow xylem cell tapered at both ends
- 17. Here cells are stimulated to grow longer
Down
- 1. an opening on the stem for gaseous exchange
- 2. a function of roots
- 3. This protects the root as it pushes and grows through the soil
- 4. cells where photosynthesis occurs in the leaf
- 7. system external structure above ground in the plant
- 8. pore in leaf which allows efficient gaseous exchange
- 9. points where leaves emerge from
- 10. found at the tip of the stem
- 11. function of the flower
- 15. dead tissue which provides support for xylem cells
- 16. this type of tissue transports materials through the plant
