whan osmotic potential is either zero or negative and pressure potential is positive then the water potential will be

1. always negative
2. always positive
3. some times negative and some times positive
4. do not show any specificity

Hello student
Correct answer is 1. always negative
Osmotic potential or solute potential are always in negative values and pressure potential is usually positive. Water potential of a solution is always less than zero of has negative value.

The correct answer is (1) always negative
Water potential = pressure potential + solute potential
From the above relation, we can se that if osmotic potential is zero or negative and pressure potential is positive then water potential will always be negative.
