Across
  1. 4. Tissue made of ctively dividing, undifferentiated cells responsible for secondary growth in plants, producing secondary xylem (wood) inward and secondary phloem outward.
  2. 5. Waxy laver on the surface of leaves to reduce transpiration
  3. 6. Cells in the epidermis of roots to increase surface area
  4. 8. Evaporation of water followed by diffusion of water vapour
  5. 10. The movement of substances in phloem tissue from source to sink
  6. 12. Protein on the cell surface membrane of companion cell that pumps out Hydrogen ions
  7. 13. Perforated end walls of sieve tube elements
  8. 15. Tissue with thin cell wall but thickened only at the corner by cellulose deposition
  9. 16. A pathway of water through cytoplasm and vacuole. Osmosis happens here since the water has to cross cell surface membrane
  10. 19. Attraction of water molecule to other molecule besides water, by hydrogen bond
  11. 21. Hairs on the surface of the leaf that reduces transpiration
  12. 23. Waterproof materials in the cell wall of xylem and schlerenchyma
  13. 24. A thin tissue, one-cell thick, surrounding vascular bundle in dicot roots. Prevent apoplast.
  14. 25. Tube-like structures of phloem
  15. 26. Cells in endodermis that doesn't have the deposition of suberin
  16. 27. Tissue with thin cell walls made of cellulose, and usually have intracellular cells
Down
  1. 1. Attraction of water molecule to another water molecule by hydrogen bond
  2. 2. Protein on the cell surface membrane of companion cell where Hydrogen ions diffuse in, bringing sucrose together with them
  3. 3. A plant that is adapted to live in an environment where water is in short supply.
  4. 4. Cells that provide energy for sieve tube elements
  5. 7. When this factor increases, transpiration rate decreases
  6. 9. Specialised parenchyma tissues for photosynthesis in the leaf.
  7. 11. Adaptation of xerophyte, where stomata is located in pits
  8. 14. Waterproof materials in the cell wall of endodermis
  9. 17. A pathway of water through cell wall
  10. 18. Thick, waterproof, waxy band in the cell wall of endodermis
  11. 20. One-cell thick tissue(usually, in some plants can be more), continuous layer outside of the plant
  12. 22. Tissue with thick cell walls, mainly due to lignin deposition (it is uniformly deposited). not for transport, but for mechanical support.
