Solution

The correct option is A DPD
The actual pressure with which water enters into a cell is 'Diffusion Pressure Deficit' or DPD. It can be calculated as the difference in the osmotic pressure and turgor pressure. Osmotic pressure causes movement of water into the cell and develops because of the solutes dissolved in the solution of cell sap. On the other hand the turgor pressure is an opposing force, which works in the direction opposite to the movement of water and prevents entry of water into the cell. Turgor pressure develops because of the entry of water into the cell.
