| Term | Definition |
|---|
| diffusion | the random movement of molecules from an area of higher concentration of those molecules to an area of lower concentration |
| osmosis | a special case of diffusion where water diffuses through a selectively permeable membrane from a region of higher water potential to a region of lower water potential |
| permeable membrane | a membrane that allows for diffusion of certain solutes and water |
| water potential | the measure of free energy of water in a solution |
| active transport | uses energy from ATP to move substances through the cell membrane against a concentration gradient, from regions of low concentration of that substance into regions of higher concentration |
| isotonic | when two solutions have the same concentration of solutes |
| hypertonic | a solution with more solute |
| hypotonic | a solution with less solute |
