Answer:
In this case, the solute concentration of the external medium is higher than that of the vacuole, which means the solute potential of the external solution is lower (more negative). Then the vacuum will lose water to reach the water balance, the volume of the protoplast will be reduced and will tend to adopt the smallest surface area per unit volume, that is, the spherical shape, and separate completely from the cell wall (cell is plasmolyzed)
