| Diffusion | Osmosis |
| Diffusion is the free movement of molecules of a substance from the region of its higher concentration to the region of its lower concentration when the two substances are in direct contact. | Osmosis is the diffusion of water molecules across a semi-permeable membrane from a more dilute solution (with a lower solute concentration) to a less dilute solution (with a higher solute concentration). |
