Novay_Z [31]

Answer:

The correct answer is - Ψ = ΨS + ΨP.

Explanation:

The movement of the water in a solution where is two different concentrations present can be determined by measuring the water potential (Ψ).

Water potential (Ψ) can be determined by the equation that depends on these two factors osmotic potential represent by ΨS and pressure potential represent by ΨP.

Ψ = ΨS + ΨP.
