Explanation:
Detailed explanation-1: -Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. For cell transport, diffusion is the movement of small molecules across the cell membrane.
Detailed explanation-2: -Diffusion refers to the process by which molecules intermingle as a result of their kinetic energy of random motion. It is the net movement of molecules or atoms from a region of high concentration to a region of low concentration. This is also referred to as the movement of a substance down a concentration gradient.
