Two potato cubes each $1 c m^{3}$ in size, were placed separately in two containers (A & B), the container (A) having water and the other (B) containing concentrated sugar solution. After $24$ hours when the cubes were examined, those placed in water were found to be firm and had increased slightly in size and those placed in concentrated sugar solution were found to be soft and had some what decreased in size.
