Across
  1. 3. Cells in an isotonic solution
  2. 4. This process uses energy
  3. 10. movement of particles from a region of higher concentration to a region of lower concentration as a result of their random movement
  4. 12. I am freely permeable to water and dissolved substances
  5. 14. The higher I am, the faster diffusion happens
  6. 16. I am a type of energy that is needed for diffusion
  7. 18. Cells in a hypertonic solution
Down
  1. 1. A measure of whether a solution will gain or lose water molecules from a different solution
  2. 2. Force inside the cell which pushes outwards, pushing the cell membrane against the cell wall
  3. 5. I only allow some things to go through
  4. 6. Also cells in a hypertonic solution
  5. 7. Movement of water molecules from a region of higher water potential to a region of lower water potential
  6. 8. I move through the cell membrane by diffusion
  7. 9. The shorter it is, the faster diffusion happens
  8. 11. Also cells in an isotonic solution
  9. 13. Cells in a hypotonic solution
  10. 15. Also cells in a hypotonic solution
  11. 17. A special type of protein molecule
