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 driving force: The driving force for osmosis is the concentration gradient of solutes. Water moves to balance the concentration of solutes on both sides of the membrane.
Consider the options: Evaluate each option based on the definition of osmosis. The correct direction is from lower solute concentration to higher solute concentration.
Eliminate incorrect options: Discard options that suggest movement based on pressure or temperature, as osmosis is primarily driven by solute concentration differences.
Select the correct answer: Choose the option that aligns with the definition of osmosis, which is the movement of water from a region of lower solute concentration to a region of higher solute concentration.
