How is diffusion different from the other types of transport

I need at least a paragraph

Diffusion is different from other types of transport as it occurs in any type of mixtures. Diffusion occurs even when two solutions are separated by a semipermeable membrane.

Explanation:

Diffusion is the movement of anything from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration. Spraying of perfume in a room is an example of diffuion, since the smell of perfume diffuses from one part of room to another. One more type of transport is osmosis. Osmosis is a process which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.
