Detailed explanation-1: -Osmosis is the movement of molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane.

Detailed explanation-2: -1: Osmosis: In osmosis, water always moves from an area of higher water concentration to one of lower concentration. In the diagram shown, the solute cannot pass through the selectively permeable membrane, but the water can.

Detailed explanation-3: -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.
