How do water molecules move during osmosis?

• A. From a region of lower solute concentration to a region of higher solute concentration
• B. From a region of higher solute concentration to a region of lower solute concentration
• C. From a region of higher pressure to a region of lower pressure
• D. From a region of lower temperature to a region of higher temperature

Answer: (A)

Verified step by step guidance

1. Understand the concept of osmosis: Osmosis is the movement of water molecules across a semipermeable membrane.
2. Identify the driving force of osmosis: Water moves to balance solute concentrations on either side of the membrane.
3. Recognize the direction of water movement: Water moves from a region of lower solute concentration to a region of higher solute concentration.
4. Consider the role of pressure and temperature: Osmosis is primarily driven by concentration gradients, not pressure or temperature differences.
5. Apply this understanding to the options given: Select the option that correctly describes the movement of water molecules during osmosis.
