Question

The relationship between water potential, solute potential and pressure potential is

• A. $\psi_{w}=\psi_{s}-\psi_{p}$
• B. $\psi_{w}+\psi_{s}=\psi_{p}$
• C. $\psi_{w}=\psi_{s}+\psi_{p}$
• D. $\psi_{w}+\psi_{p}=\psi_{s}$

Answer 1

Answer: (C)

Water potential of a cell is affected by both solute and pressure potential. The relationship between water potential, solute potential and pressure potential is
$\psi_{w}=\psi_{s}+\psi_{p}$
