| Diffusion | Movements of molecules from high concentrations areas to low concentrations areas. |
| Osmosis | type of diffusion that moves water from high water content to low water content. |
| high water content aka | low solute |
| low water content aka | high solute |
| Tonicity | amount of solute in a solution |
