Answer:
The answer is Osmosis is specific to molecule movement and does not require energy.
Explanation:
Osmosis a type of passive diffusion wherein substances pass through the semi-permeable cell bilayer and relies on the concentration gradient of a specific molecule. This usually involves water, carbon dioxide, and oxygen and they move from high to low concentrations or electrochemical gradient.
To demonstrate, a glass with water plus sugar is placed inside with a semi-permeable membrane in between. The solute (sugar) will not pass through as it's too big for the membrane so the solvent (water) will be the one that will cross the membrane, from high to low concentrations.
