Understand the concept of osmosis: Osmosis is the movement of water across a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration.
Identify the driving force of osmosis: The process is driven by the concentration gradient of solutes, not by pressure differences.
Recognize the role of the semipermeable membrane: This membrane allows only water molecules to pass through, not solute particles, which is crucial for osmosis.
Consider the implications of solute concentration: Water moves to balance the solute concentrations on both sides of the membrane, aiming to reach equilibrium.
Apply this understanding to the given options: The correct direction of water movement during osmosis is from a region of lower solute concentration to a region of higher solute concentration.
