Detailed explanation-1: -Osmosis refers to the movement of fluid across a membrane in response to different concentrations of solutes on the two sides of the membrane. The movement of fluid is toward the more concentrated solution.

Detailed explanation-2: -Water moves across cell membranes by diffusion, in a process known as osmosis. Osmosis refers specifically to the movement of water across a semipermeable membrane, with the solvent (water, for example) moving from an area of low solute (dissolved material) concentration to an area of high solute concentration.

Detailed explanation-3: -Osmosis is the movement of water molecules from its region of higher concentration to its region of lower concentration through a membrane.
