The real forces responsible for the movement of water from one cell to another cell is mainly

Options

  1. AOsmotic Pressure (OP)
  2. BTurgor Pressure (TP)
  3. CDiffusion Pressure Deficit (DPD)
  4. Dimbibition

Correct answer

C. Diffusion Pressure Deficit (DPD)

Step-by-step solution

The net force with which water is drawn into a cell is equal to difference of OP and TP, known as diffusion pressure deficit or suction pressure. DPD of pure water is maximum ( 1236 ~atm ) solvent moves from cell of low DPD to high DPD. DPD, or SP = OP - TP .
