| osmotic pressure | the pressure that must be applied to prevent osmotic movement across a selectively permeable membrane |
| hypotonic | a solution in which the concentration of solute is greater outside of the cell |
| hypertonic | a solution in which the concentration of solute is greater inside of the cell |
| isotonic | a solution in which the concentration of solute is the same inside and outside of the cell |
| osmosis | the diffusion of water through a selectively permeable membrane |
| aquaporin | a water channel protein |
| facilitated diffusion | the process in which molecules pass through proteins to enter the cell |
| diffusion | the proces by which particles move from an area of high concentration to an area of low concentration |
