tonicity
|
Explanation:
Detailed explanation-1: -Diffusion is defined as the net movement of molecules from an area of greater concentration to an area of lesser concentration. The molecules in a gas, a liquid or a solid are in constant motion due to their kinetic energy. Molecules are in constant movement and collide with each other.
Detailed explanation-2: -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-3: -The movement of molecules from their lower concentration to their higher concentration through a cell membrane is called active transport.
