Detailed explanation-1: -Osmosis can be defined as the spontaneous movement of solvent molecules through a semi-permeable membrane from a lower-concentration solution to a higher-concentration solution.
Detailed explanation-2: -Osmosis is the diffusion of water across a partially permeable membrane from a dilute solution (high concentration of water) to a concentrated solution (low concentration of water). In the diagram, the concentration of sugar is initially higher on the right side of the membrane.
Detailed explanation-3: -Osmosis is the diffusion of water molecules, from a region where they are in higher concentration, to a region where they are in lower concentration, through a partially permeable membrane.
Detailed explanation-4: -Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. The solvent moves to dilute the concentrated solution and equalize the concentration on both sides of the membrane.
Detailed explanation-5: -Osmosis is the process of net movement of water across a permeable membrane driven by a difference in solute concentration on two sides of the membrane.
