Which of the following statements about osmosis is false?

• A. In osmosis, water moves until equilibrium is reached, at which point there is no net movement of water across the membrane.
• B. Osmosis is the diffusion of solute molecules across a selectively permeable membrane from high solute concentration to low solute concentration.
• C. Osmosis is the net movement of water across a selectively permeable membrane from a region of higher water potential (lower solute concentration) to lower water potential (higher solute concentration).
• D. Osmosis requires a selectively permeable membrane that is permeable to water but not to at least one solute.

Answer: (B)
