Diffusion and osmosis are two processes that involve the movement of molecules from a region of higher concentration to a region of lower concentration.
Diffusion is the random movement of molecules from an area of high concentration to an area of low concentration. This process is driven by the kinetic energy of the molecules and is not dependent on an external force. Diffusion occurs in all types of substances, including gases, liquids, and solids.
Osmosis is the process of water molecules moving from an area of low solute concentration to an area of high solute concentration. This process is driven by the difference in pressure between the two areas and is dependent on the presence of a semi-permeable membrane. Osmosis is important for the regulation of water in living cells and is the primary mechanism by which cells absorb water.
In summary, diffusion is the random movement of molecules from an area of high concentration to an area of low concentration, while osmosis is the movement of water molecules from an area of low solute concentration to an area of high solute concentration.
