Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. It is a passive process, meaning it does not require energy input (like ATP) from the cell. Instead, it occurs due to the random motion of particles and the concentration gradient. Over time, diffusion leads to an equal distribution of particles in the available space.
