The movement of solutes from a higher concentrated area to a low concentrated area is called diffusion.
Diffusion is a fundamental process in biology and chemistry where molecules move from an area of higher concentration to an area of lower concentration. This movement continues until the concentration of the solute is uniform throughout the system. Diffusion is a passive process, meaning it does not require energy input from the cell. It plays a crucial role in various biological processes, such as the exchange of gases in the lungs and the transport of nutrients and waste products in and out of cells.
