During osmosis across a selectively permeable membrane, in which direction will water molecules move overall?
A
Only from the hypertonic side to the isotonic side, independent of membrane permeability
B

C
From the side with lower solute concentration (higher water potential) to the side with higher solute concentration (lower water potential)
D
Equally in both directions with no net movement, regardless of solute concentrations
