Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. It occurs due to the random movement of molecules and is temperature-dependent. Diffusion is important in processes such as gas exchange in the lungs and the absorption of nutrients from the small intestine.
Osmosis, on the other hand, is the movement of water molecules across a semipermeable membrane from an area of high water concentration to an area of low water concentration. In other words, it is the diffusion of water molecules. Osmosis is essential for many biological processes such as the transport of water from the roots to the leaves of plants and the regulation of water balance in animal cells.
