Explanation of suction force of plant cell

Question

Give a brief explanation of suction force of the plant cell. Does the suction force make probable or make tricky the entrance of water in the cell?

Answer 1

The suction force (or SF) is osmotic pressure of the plant cell vacuole, that is, of the vacuolar internal solution. Because the vacuolar solution is hypertonic in comparison to the cytosol it absorbs water thus raising the cytosol concentration. With osmotic action of vacuole the cytosol becomes hypertonic in relation to exterior and more water enters in the cell.
