Across
  1. 3. the concentration of particles is the same on both sides of a semipermeable membrane
  2. 4. movement of a substance from low concentration to high concentration across a semipermeable membrane with the aid of transmembrane protein
  3. 7. solution where the concentration of particles is greater out of the cell; net movement of water is out of the cell, cell shrinks
  4. 9. type of membrane that regulates the movement of particle across it
  5. 14. the uptake or release of material via vesicles
  6. 15. channel that opens and closes in response to changes in the membrane potential
  7. 16. movement of a substance from high concentration to low concentration across a semipermeable membrane until an equilibrium is established
  8. 17. is a measure of the effect of the osmotic pressure gradient of two solutions separated by a semipermeable membrane on the cell membrane.
  9. 18. channel that opens and closes in response to physical deformation of receptors
Down
  1. 1. solution where the concentration of particles is the same both in and out of the cell; no net movement of water, cell stays the same size
  2. 2. channel that opens with binding of specific chemical
  3. 5. solution where the concentration of particles is less out of the cell; net movement of water is into the cell, cell swells
  4. 6. uptake of liquids or material via vesicles
  5. 8. diffusion with the aid of transmembrane protein
  6. 9. active transport driven by the concentration gradient establish through primary active transport; uses ATP indirectly
  7. 10. differences in amount of substances in a area
  8. 11. active transport that directly using chemical energy supplied by the cell; uses ATP directly
  9. 12. release material out of the cells
  10. 13. the pressure required to prevent osmosis out of a cell and into the solution
