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

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.
