Difference between diffusion and osmosis
| Diffusion | Osmosis |
|---|
| Movement of molecules from an area of higher concentration to an area of lower concentration | Movement of solvent molecules from an area of lower solute concentration to an area of higher solute concentration through a semi-permeable membrane |
| Can occur in any medium (air, liquid, gas) | Occurs only in liquid or gas |
| Does not require a semi-permeable membrane | Requires a semi-permeable membrane |
| Can occur in both living and non-living systems | Mainly occurs in living systems |
| Does not involve the movement of water molecules | Involves the movement of water molecules |
| Does not require energy | Does not require energy, but may require pressure |
| Examples include the movement of gases in the lungs and the diffusion of perfume in a room | Examples include the movement of water in plant cells and the movement of water and ions in the kidneys |
