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

Detailed explanation-2: -Osmosis is the net movement of water across a selectively permeable membrane driven by a difference in solute concentrations on the two sides of the membrane. A selectively permiable membrane is one that allows unrestricted passage of water, but not solute molecules or ions.

Detailed explanation-3: -Osmosis is the process in which there is the movement of molecules towards their lower concentration through the membrane (such as cell membrane). Water is not the only molecule that moves through osmosis. Other molecules which use osmosis for their movement are carbon dioxide, oxygen, and other simple molecules.

Detailed explanation-4: -Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of lower concentration solution (i.e., higher concentration of water) to an area of higher concentration solution (i.e., lower concentration of water). Water moves into and out of cells by osmosis.
