Question

Water potential can be obtained by

• A. OP + TP
• B. OP $=$ WP
• C. P + $\pi$
• D. OP - DPD

Answer 1

The correct option is C P + $\pi$

Water potential is the algebraic sum of osmotic potential and pressure potential. Here, osmotic potential has a negative sign and pressure potential has a positive sign. Water potential of solution is always negative.
