Question

A hypothetical arrangement of plant cells $(\text{A, B, C}$ and $\text{D})$ is given below–

• A. $\text{D → B → C → A}$
• B. $\text{A → C → B → D}$
• C. $\text{D → B → A → C}$
• D. $\text{D → A → C → B}$

Answer 1

The correct option is A $\text{D → B → C → A}$

We know that, $\text{DPD = - Ψw}$
(Low $\text{DPD}$ to high $\text{DPD}$)
Normally water potential is from high potential to low potential.
So, DPD or diffusion pressure deficit is from low DPD to high DPD.
So, the correct sequence of movement of water is $\text{D → B → C → A}$
