- A Solute concentration in it decreases
- B Applied pressure rises above atmospheric
- C Solute concentration in it increases
- D Temperature drops, regardless of solutes
Correct answer: C. Solute concentration in it increases
Explanation: Adding solutes lowers (makes more negative) the water potential of a solution, since solute particles reduce the free energy of water molecules available to do work.
Concept context
Water and mineral absorption, the ascent of sap, transpiration, and phloem transport via the pressure flow hypothesis.
