What is meant by suction force of the plant cell? Does the suction force facilitate or make difficult the entrance of water in the cell?


The suction force (SF) is the osmotic pressure of the plant cell vacuole, i.e., of the vacuolar internal solution.

Since the vacuolar solution is hypertonic in comparison to cytosol it attracts water then increasing the cytosol concentration. With the osmotic action of the vacuole the cytosol becomes hypertonic in relation to the exterior and more water enters the cell.
