| Diffusion | Osmosis |
| Movement of molecule from high concentration to low concentration. | Movement of solvent across a semipermeable membrane from high to low solvent concentration. |
| Both solute and solvent move. | Only solvent moves |
Explanation:
- Osmosis is defined as the tendency of a fluid, usually water to pass through a semipermeable membrane into a solution where the solvent concentration is low and the solute concentration is higher.
- Here it is given that “Osmosis is the diffusion of a solution of a weaker concentration” into a solution of stronger concentration when - both are separated by a semi-permeable membrane.” in this statement, the solvent movement is not specified, since osmosis involves movement of solvent only.
The error of the given statement is that the movement of the solvent is not specified.
