A concentration gradient must exist.

Diffusion is the passive movement of particles from an area of higher concentration to an area of lower concentration; it proceeds until dynamic equilibrium is reached. Hypotonic or hypertonic conditions refer specifically to solute concentrations relative to another solution (important for osmosis), but are not required for diffusion in general.
