Detailed explanation-1: -In biology, osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell’s partially permeable membrane.
Detailed explanation-2: -Osmosis refers to the movement of fluid across a membrane in response to differing concentrations of solutes on the two sides of the membrane. Osmosis has been used since antiquity to preserve foods by dehydration with salt or sugar. The removal of water from a tissue by salt was referred to as imbibition.
Detailed explanation-3: -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-4: -Osmosis is the passage of water molecules across a semi-permeable membrane from a solution with a high concentration to a solution with a lower concentration. It is a generalized process in which gases also participate.
Detailed explanation-5: -The correct definition of osmosis is “ Movement of solute molecules from lower concentration to a higher concentration of solution through a semipermeable membrane”.
