Osmosis | Diffusion |
It is the movement of solvent from lower concentration to the higher concentration of solute. | It is the movement of solute from higher concentration to the lower concentration of solute. |
It requires semipermeable membrane. | It does not require semipermeable membrane. |
It depends on the solute potential. | It does not depend on the solute potential. |
It is opposed by turgor or hydrostatic pressure. | Turgor or hydrostatic pressure do not operate on diffusion. |
