How do diffusion and osmosis differ from one another?

Diffusion and osmosis differ because diffusion is the process by which molecules spread out, or move from areas with high concentration to low concentration, and osmosis is the diffusion of water.

Osmosis is a type of diffusion relating to water. It is usually used to describe the diffusion of water across a membrane (such as the cell membrane).

Osmosis is also defined as the flow of solvent from a region of higher pressure toward a region of low pressure.
