Across
  1. 3. Swollen starchy stems.
  2. 5. Horizontal below-ground stems.
  3. 8. Found in ferns, conifers, and flowering plants. Provides more support.
  4. 10. ________ cells are photosynthetic and open/close stomata by filling with water.
  5. 12. Soft & Squishy, where most photosynthesis occurs.
  6. 14. Laid end to end like vessel elements, no nuclei at maturity (but alive).
  7. 16. Function is to seal plant surface.
  8. 18. Function is growth.
  9. 20. Most _______________ occurs in the mesophyll.
  10. 21. Vascular tissue in the leaves (xylem and phloem).
  11. 23. Thickened cell walls, flexible support,water movement.
  12. 24. 2nd major component of cell walls, gives lumber it's structure.
Down
  1. 1. Conducts food DOWN. Cells: sieve tubes and companion cells.
  2. 2. Waxy epidermis, protects leaf and prevents water loss.
  3. 4. Horizontal above-ground stems.
  4. 6. Three Main Sections of a leaf: Epidermis, __________, and Veins.
  5. 7. Openings in leaf for gas exchange.
  6. 9. Outermost layer in young plant tissues.
  7. 11. Found only in flowering plants! Conducts more water.
  8. 12. Replaces epidermis in woody tissue.
  9. 13. Function is Photosynthesis, growth, storage, movement, support
  10. 15. Fibrous cells with thick cell walls.
  11. 17. _________ Cells Support transport of glucose.
  12. 19. _______ Tissue Function is to move water and nutrients.
  13. 22. Conducts water and minerals UP. Cells: vessel elements and tracheids
  14. 23. Vascular ________ Cylindrical meristem gives rise to transport tissue.
