AFrom lower to higher water potential
BFrom lower to higher solute concentration
CFrom higher to lower solute concentration
DFrom higher to lower water potential
Answer & Solution
Correct answer: D. From higher to lower water potential
1. When the total water potentials of two systems differ, water moves to equilibrate them.
2. It moves from the compartment with the higher water potential to the compartment with the lower water potential.
3. That movement brings the difference between the two systems back towards zero.
4. Water responds only to the difference in water potential, not to any single component on its own.
