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
${\psi }_w={\psi }_s+{\psi }_p$
