Movement of particles from a region of high concentration to a region of low concentration
Explanation:
Diffusion can be defined as the movement of particles from a region of high concentration to a region of low concentration.
Diffusion is a special type of diffusion that involves movement of solute molecules from a region of a high concentration to a region of high concentration until equilibrium is achieved.
Diffusion is a passive transport of particles, which means it does not involve use of energy in the form of ATP like the case of active transport.
