Sugar solution is hypertonic to cell sap of potato, whereas water acts as a hypotonic solution to it. When the potato strip is placed in water, its cells will gain water by osmosis, resulting in increase in size of potato strip.
When the potato strips are put in sugar solution of different concentrations, the cells will lose water resulting in decrease in the size of strip. As only potato strip placed in liquid ‘Q’ shows increase in length, this shows that liquid ‘Q’ is water.
