Question

If ${Ψ}_W=$ water potential; ${Ψ}_S=$ solute potential; ${Ψ}_P=$ pressure potential, then select the correct equation showing their inter-relation.

• A. ${Ψ}_W={Ψ}_S−{Ψ}_P$
• B. ${Ψ}_W={Ψ}_S+{Ψ}_P$
• C. ${Ψ}_S={Ψ}_W+{Ψ}_P$
• D. ${Ψ}_W={Ψ}_S={Ψ}_P$

Answer 1

Answer: (B)

${Ψ}_W={Ψ}_S+{Ψ}_P$
where ${Ψ}_W=$ water potential,
${Ψ}_S=$ solute potential and
${Ψ}_P=$ pressure potential.
