Question: Simple diffusion is defined as the movement of?
Simple diffusion is defined as the movement of molecules from an area of high concentration to an area of low concentration, without the need for any energy input or membrane transport proteins. This process occurs spontaneously due to the random motion of molecules and their tendency to spread out evenly in a given space. Simple diffusion can occur across any permeable membrane, such as the plasma membrane of a cell or the capillary wall of a blood vessel.
