Difference between Diffusion and Osmosis
Difference between Diffusion and Osmosis are in tabular form below –
No. |
Diffusion |
Osmosis |
Definition |
||
1. | A movement of molecules from region of high to low concentration until they spread in the media, this is known as Diffusion. | A movement of solvent molecules through semipermeable membrane and from region of higher free energy to region of lower free energy, this is known as Osmosis. |
Involvement |
||
2. | In the diffusion, semipermeable membrane is not involved. | In the Osmosis, semipermeable membrane is involved. |
Diffusing molecules |
||
3. | In the diffusion, both solvent and solute molecules are able to diffuse. | In the osmosis, only solvent molecules are able to diffuse. |
Semipermeable membrane |
||
Semipermeable membrane is not required in the diffusion. | Semipermeable membrane is required in the osmosis. | |
Medium |
||
5. | Diffusion takes place in all liquid, solid and gases medium. | Osmosis takes place in only liquid medium. |
Particles flow |
||
6. | In the diffusion, particles can flow in all the directions. | In the osmosis, particles can flow only in one direction. |
