What is the effect of maltose solution on an onion cell?Thank you :)

Maltose is a  disaccharide consisting of two molecules of
glucose joined together by dehydration synthesis. If onion tissue was surrounded by a
solution of maltose, there would be a greater concentration of solute outside the cell
relative to inside. The membrane is selectively permeable. The freshwater inside the
onion cells would be in greater concentration relative to the outside environment, due
to the presence of the solute. As a result, osmosis would occur and water would move out
of the onion cells from high concentration inside, to low concentration outside. This
effect is known as plasmolysis and the onion cell would dehydrate and shrink. The cell
would lose turgor, which is the pressure of the liquid inside pressing against the cell
wall. If enough fluid is lost, the rigid, non-living cell wall may even
collapse.
