Question

If $\Psi_{W}=$ water potential; $\Psi_{S}=$ solute potential; $\Psi_{P}=$ pressure potential, then select the correct equation showing their inter-relation.

• A. $\Psi_{W}= \Psi_{S}-\Psi_{P}$
• B. $\Psi_{W}= \Psi_{S}+\Psi_{P}$
• C. $\Psi_{S}= \Psi_{W}+\Psi_{P}$
• D. $\Psi_{W}= \Psi_{S}=\Psi_{P}$

Answer 1

Answer: (B)

$\Psi_{W}=\Psi_{S}+\Psi_{P}$
where $\Psi_{W}=$ water potential,
$\Psi_{S}=$ solute potential and
$\Psi_{P}=$ pressure potential.
