Difference Between Diffusion and Osmosis

Difference Between Diffusion and Osmosis:

The following are the points of difference between Diffusion and Osmosis-

Diffusion can take place in any medium.Osmosis occurs only in a liquid medium.
It is a movement of small-sized particles of different substances according to their concentration gradients.It is the movement of only water or solvent molecules according to the gradient of their chemical potential.
A semipermeable membrane is not required.It requires a semipermeable membrane.
It is dependent upon the free energy of the molecules of diffusing substance only; the presence of other substances in the system is of no importance.Though it is the diffusion of solvent molecules only, yet influenced by the presence of other substances (solutes) in the system.
A turgor or hydrostatic pressure does not develop.A turgor or hydrostatic pressure develops due to osmosis.
Diffusion continues till concentration becomes the same throughout the available space.Equalization of concentration of solvent is not possible.
Factors like water potential, solute potential and pressure potential do not affect diffusion.Water potential, solute potential and pressure potential do not affect osmosis in a living system.
