Question

Water potential of a flaccid cell will be

• A. ${\Psi }_w$ = ${\Psi }_s$
• B. ${\Psi }_s$= ${\Psi }_p$
• C. ${\Psi }_w$ = 0
• D. ${\Psi }_w$ = ${\Psi }_s$ - ${\Psi }_p$

Answer 1

The correct option is C ${\Psi }_w$ = 0

Pressure potential is negative in a plasmolysed cell and xylem vessel, positive for a turgid cell and zero for aflaccid cell.

So the correct answer should be option "ψw =0".
