Across
  1. 1. Pores in the epidermis of a leaf, bounded by two guard cells and needed for efficient gas exchange.
  2. 7. A basic plant tissue typically used as packing tissue between more specialized structures; it is metabolically active and may have a variety of functions such as food storage, support, and transport via symplast and apoplast pathways.
  3. 10. The living pathway made of interconnecting protoplasts extending throughout the plant
  4. 11. The transport of assimilates through a plant, in phloem tissue.
  5. 13. Strengthening tissue in a plant, formed from cells with thickened (typically lignified) walls.
  6. 14. Tissue containing xylem vessel elements and other types of cells, responsible for the transport of water through a plant.
  7. 15. The internal tissue of a leaf blade with chloroplasts for photosynthesis.
  8. 17. An area in which sucrose is loaded into the phloem (e.g. a photosynthesizing leaf)
  9. 18. A complex organic polymer deposited in the cell walls of many plants, making them rigid and woody.
  10. 19. Tissue containing sieve tubes and other types of cells, responsible for the translocation of assimilates such as sucrose through a plant.
Down
  1. 1. An area in which sucrose is taken out of the phloem (e.g. roots)
  2. 2. The non-living pathway made of interconnected cell walls extending throughout the plant.
  3. 3. A modified form of parenchyma in which the corners of the cells have extra cellulose thickening, providing extra support.
  4. 4. A flowering plant with an embryo that bears two seed leaves.
  5. 5. Plants adapted to survive in conditions where water is in short supply.
  6. 6. A protective, waxy or hard layer covering the epidermis of a plant.
  7. 8. A flowering plant with an embryo that bears a single seed leaf.
  8. 9. The loss of water vapor from a plant to its environment by diffusion down a water potential gradient.
  9. 12. The upper layer of mesophyll.
  10. 16. The lower layer of mesophyll.
