Q. Which process describes movement of water across a semipermeable membrane from low solute concentration to high solute concentration?
✅ Correct Answer: (B)
Osmosis
Explanation: Osmosis is the passive movement of water across a semipermeable membrane toward higher solute concentration. Diffusion refers to movement of solutes from high to low concentration. Active transport requires energy to move substances against their gradient. Facilitated diffusion is passive transport of solutes via carriers/channels (not water specifically).
