Across
  1. 3. a cellular feature found in the roots of all higher plants
  2. 9. bidirectional
  3. 12. the inner tissue of a leaf, containing many chloroplasts
  4. 13. interconnects all organs and transports water
  5. 14. process by which plants maintain their water content despite the constant water loss due to transpiration
  6. 15. a major constituent of cork
  7. 16. thin areas on the secondary cell walls of plants
  8. 19. makes a major part of ground tissues
  9. 21. Draw only the shape without its specific cells
  10. 22. a thin layer of parenchymatous or sclerenchymatous cells that surrounds the stele in most vascular plants
  11. 23. The surface epithelium of the skin, overlying the dermis
  12. 25. unidirectional
  13. 26. allows for the water to stick to the organic tissues of plants
  14. 27. the way trough the cell wall
  15. 29. present in the vascular bundles of dicot stems
  16. 30. a layer of closely packed cells found under the epidermis on the upper layer of a leaf
Down
  1. 1. A cambium occurring between vascular bundles
  2. 2. endodermal cells present in older roots that have not undergone suberization and are devoid of Casparian strips
  3. 4. strengthening tissue in a plant, formed from cells with thickened, typically lignified, walls
  4. 5. the way trough the cell
  5. 6. keeps the water molecules together
  6. 7. the exhalation of water vapor through the stomata
  7. 8. pores in the epidermis of the leaf or stem of a plant, forming a slit of variable width which allows movement of gases in and out of the intercellular spaces
  8. 10. Draw with the shape aslo with the specific cells
  9. 11. an outer or surrounding layer of an organ or body part
  10. 12. a large strengthened vein along the midline of a leaf
  11. 17. tissue strengthened by the thickening of cell walls, as in young shoots
  12. 18. the innermost layer of cortex in land plants
  13. 20. a measure of the potential energy in water as well as the difference between the potential in a given water sample and pure water
  14. 24. occurs when water changes from a liquid state to a gaseous state
  15. 28. a complex organic polymer deposited in the cell walls of many plants, making them rigid and woody
