Detailed explanation-1: -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-2: -In osmosis, water moves from areas of low concentration of solute to areas of high concentration of solute.

Detailed explanation-3: -Water transport across cell membranes occurs by diffusion and osmosis. The effective osmolality of a biological fluid is determined by the total solute concentrations and the solutes’ permeabilities, relative to water.

Detailed explanation-4: -Introduction. In physiology, osmosis (Greek for push) is the net movement of water across a semipermeable membrane.[1][2] Across this membrane, water will tend to move from an area of high concentration to an area of low concentration.

Detailed explanation-5: -Osmosis is the spontaneous net movement of water across a semipermeable membrane from a region of low solute concentration to a more concentrated solution, up a concentration gradient. This equalizes concentrations on both sides of the membrane.
