Understand the concept of osmosis: Osmosis is the movement of water molecules across a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration.
Identify the role of the semipermeable membrane: This membrane allows only certain molecules, like water, to pass through while blocking others, such as solute particles.
Recognize the driving force of osmosis: The process is driven by the concentration gradient of solutes, where water moves to balance the solute concentrations on both sides of the membrane.
Consider the options given: Analyze each option to determine which one correctly describes the movement of water molecules during osmosis.
Select the correct option: Based on the understanding of osmosis, choose the option that states water moves from a region of lower solute concentration to a region of higher solute concentration.
