Across
  1. 1. openings or pores in the epidermis of leaves
  2. 3. layer of tissue between the vascular tissue and the epidermis
  3. 7. tough and waterproof outer layer cork cells in woody plants
  4. 9. stems that run almost parallel to the ground and can give rise to new plants at the nodes
  5. 10. protective layer covering the epidermal cells of leaves and other parts and limiting water loss
  6. 11. ground tissue towards the interior of the vascular tissue in a stem or root
  7. 13. vascular tissue in the root is arranged in the inner portion of the root
  8. 15. dead cells that have heavily thickened walls containing lignin
  9. 18. support tissue with irregular thick walls
  10. 19. layer of tissue between the vascular tissue and the epidermis
Down
  1. 2. modified branches appearing as sharp outgrowths that protect the plant
  2. 4. outermost single layer of cells covering and protecting stem, root, leaf, and other parts of a plant
  3. 5. type of plant tissue actively involved in photosythesis, cellular respiration, and food storage
  4. 6. transport organic compounds from the site of photosynthesis to the other parts of plants
  5. 8. hair-like structures on the epidermal surface of a plant
  6. 9. linear appendage found at the base of the petiole of a leaf
  7. 12. transports water and nutrients from the roots to different parts of the plant
  8. 14. thin and usually flattened blade of a leaf
  9. 16. outermost cell layer of root giving rise to the branches in roots
  10. 17. modified stem that grows horizontally underground and has nodes and internodes
