En la ÓSMOSIS, un disolvente (a menudo agua) se mueve desde una zona de baja concentración de solutos hacia una zona de alta concentración de solutos, a través de una membrana semipermeable. Aquí, las moléculas de agua se difunden en la disolución concentrada de azúcar debido a que son lo suficientemente pequeñas como para poder moverse a través de la membrana; las moléculas de azúcar, de mayor tamaño, son incapaces de atravesarla. La ósmosis finaliza cuando las dos disoluciones alcanzan la misma concentración a cada lado de la membrana. La tendencia natural de las moléculas a moverse desde zonas de alta concentración hacia zonas de baja concentración se llama DIFUSIÓN.
