Select the correct statement from the following.
Select the correct statement from the following.
Options
- AIn a fully turgid cell, TP = OP.
- BIn a fully turgid cell, TP > OP.
- CIn a fully turgid cell, DPD = OP.
- DTurgor pressure decreases when the cell is placed in hypotonic solution.
Correct answer
A. In a fully turgid cell, TP = OP.
Step-by-step solution
The diffusion pressure deficit (DPD) of a cell is given by the relation DPD = OP - TP, where OP is the osmotic pressure and TP is the turgor pressure.
When a cell is fully turgid, it cannot absorb any more water, which means its DPD becomes zero.
Substituting DPD = 0 in the equation, we get 0 = OP - TP, which implies OP = TP.
When a cell is placed in a hypotonic solution, water enters the cell due to endosmosis, causing the turgor pressure to increase, not decrease.
Answer: In a fully turgid cell, TP = OP.
