Across
  1. 1. high solute concentration, so less free water molecules
  2. 4. basic fabric of the cell membrane
  3. 6. the pressure in fluid measured when its at equal
  4. 7. simulates how a cell membrane is selectively permeable. It allows small molecules like glucose to pass through, but not larger molecules like starch.
  5. 8. loss of water from the cell
  6. 9. equal solute concentration, so equal free water molecules
  7. 11. the minimum pressure that must be applied to a solution
  8. 12. proteins to big to pass through the lipid bilayer
  9. 15. tonicity is a measure of the effective osmotic pressure gradient
  10. 16. only allowing some molecules to pass through the cell membrane
  11. 17. movement of particles from an area of HIGH concentration to low concentration w/o any energy. Particles move down their concentration gradient
  12. 18. water loving
Down
  1. 1. low solute concentration, so a lot of free water molecules
  2. 2. group of organic compounds
  3. 3. does not require energy and includes the process of osmosis
  4. 5. describes the characteristics of the cell membrane that make it selectively permeable
  5. 6. water fearing
  6. 10. Diffusion of large molecules, like sugar molecules, across membranes with the help of transport proteins.
  7. 13. Diffusion of water Molecules across membranes.
  8. 14. Gradient change of solutes
