Explanation:
Detailed explanation-1: -The kinetic energy of the molecules results in random motion, causing diffusion. In simple diffusion, this process proceeds without the aid of a transport protein. It is the random motion of the molecules that causes them to move from an area of high concentration to an area with a lower concentration.
Detailed explanation-2: -The movement of molecules from an area of higher concentration to an area of lower concentration is called diffusion.
Detailed explanation-3: -Facilitated diffusion is a passive movement of molecules across the cell membrane from the region of higher concentration to the region of lower concentration by means of a carrier molecule.
