Across
  1. 2. solute cross the membrane down the concentration
  2. 5. not all substances can pass through
  3. 11. movement of large particles across the membrane
  4. 13. not embedded in the lipid layer
  5. 14. fatty acid tails
  6. 15. solute cross the membrane down the concentration gradient with the help of proteins
  7. 16. small amount of nutrients are transported into the cell
  8. 17. large particles are imported into the cells
  9. 18. carbohydrate-lipid
  10. 19. water enters the cell
  11. 21. cell transport not requiring energy
Down
  1. 1. channels connecting adjacent plant cells
  2. 3. firmly bound to the membrane
  3. 4. total concentration of all solutes in the solution
  4. 6. extend across the membrane
  5. 7. transfer molecules across membrane
  6. 8. phospate group
  7. 9. cell transport requiring energy
  8. 10. carbohydrate-protein
  9. 12. cell loses water
  10. 20. no movement of water within cells
