An experiment was performed to examine how the concentration of sucrose solution affected cells in a plant tissue. After 2 hours, the cylinders were taken out, dried with blotting paper and weighed again. The percentage change in mass for each cylinder was noted. The graph presents the findings of this investigation. Which row gives the explanation for the results if plant tissue cells were placed in a sucrose solution of $0.45\,\text{mol dm}^{-3}$?
