Diffusion is the process by which molecules freely move in an out of cells. When the concentration of molecules is higher outside of the cells more molecules will enter the cell or cells than leave. Diffusion is driven by the largely random movements of molecules within a solution.
Diffusion is the movement of particles across a membrane or the collision of molecules resulting in them to spread apart. Diffusion in cells helps exchange materials.

Cell utilize this process to transport materials across the cell membrane without the expenditure of energy.
