| facilitated diffusion | movement of specific molecules across cell membranes through protein channels |
| aquaporin | A transport protein in the plasma membrane of a plant or animal cell that specifically facilitates the diffusion of water across the membrane (osmosis). |
| osmosis | diffusion of molecules through a semipermeable membrane from a place of higher concentration to a place of lower concentration until the concentration on both sides is equal |
| isotonic | of or involving muscular contraction in which tension is constant while length changes |
| hypertonic | (of a solution) having a higher osmotic pressure than a comparison solution |
| hypotonic | (of a solution) having a lower osmotic pressure than a comparison solution |
| osmotic pressure | (physical chemistry) the pressure exerted by a solution necessary to prevent osmosis into that solution when it is separated from the pure solvent by a semipermeable membrane |
