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