Which cell has maximum diffusion pressure deficit?
Which cell has maximum diffusion pressure deficit?
Open in App
Solution
The correct option is A Flacid cell
Diffusion pressure deficit or DPD is the difference between the pressure of a solution and a pure solvent. It is also called as suction pressure. In order to achieve the equilibrium or attain zero value of DPD, the solvent from low solute concentration or low DPD to high solute concentration or high DPD. In other words, the diffusion pressure deficit is equal to the total of osmotic pressure and turgor pressure. DPD is maximum in pure water. In a flaccid cell, there is no movement of water. In a flaccid cell, there is no turgor pressure. Hence, DPD is equal to the osmotic pressure.Thus, the correct answer is 'Flaccid cell.'
