Question

Difference between osmotic pressure and turgor pressure is

• A. Diffusion Pressure Deficit (DPD)
• B. Transpiration pull
• C. Osmotic potential
• D. Solute potential

Answer 1

The correct option is A Diffusion Pressure Deficit (DPD)

• The difference between osmotic pressure and turgor pressure gives the diffusion pressure deficit. Mathematically, DPD= Osmotic pressure (OP) – Turgor pressure (TP).
• DPD is the pressure difference between pure water and solution.
• Osmotic pressure is the minimum pressure that needs to be applied on the solution to prevent the inward flow of its pure solvent across a semipermeable membrane and turgor pressure is the pressure inside the cell pushes plasma membrane against the cell wall of the plant cell.
  Hence, option A is correct.
