Q896

Arrange root hair cell inner, cortical cell and mesophyll cell in ascending order of DPD

A.
Mesophyll cell, Root hair cell and Cortical cell
B.
Cortical cell, Mesophyll cell and Root hair cell
C.
Root hair cell, Cortical cell and Mesophyll cell
Answer
D.
Root hair cell, Mesophyll cell and Cortical cell

Answer: Option C

Solution

Answer: Option C
Solution:
The difference between the diffusion pressure of pure solvent and solution is called diffusion pressure deficit (DPD).
It is a reduction in the diffusion pressure of the solvent in the solution over its pure state due to the presence of solutes in it and forces opposing diffusion.
In ascending order of DPD, it can be arranged as Root hair > Cortical cell > Mesophyll cell.
