Which of the following best describes osmosis?
A
The movement of gases from an area of high pressure to an area of low pressure.
B
The movement of solute molecules from an area of low concentration to an area of high concentration using energy.
C
The movement of water molecules from an area of low water concentration to an area of high water concentration through any membrane.
D
The movement of water molecules from an area of high water concentration to an area of low water concentration across a selectively permeable membrane.
검증된 단계별 안내1
Step 1: Understand the concept of osmosis. Osmosis is a type of passive transport, meaning it does not require energy, and it specifically involves the movement of water molecules across a selectively permeable membrane.
Step 2: Recall the direction of water movement in osmosis. Water molecules move from an area of high water concentration (or low solute concentration) to an area of low water concentration (or high solute concentration).
Step 3: Identify the role of the selectively permeable membrane. This membrane allows only certain molecules, such as water, to pass through while blocking others, such as solutes.
Step 4: Analyze the options provided. Eliminate choices that do not describe the movement of water molecules or that involve energy, as osmosis is a passive process.
Step 5: Select the correct description of osmosis: 'The movement of water molecules from an area of high water concentration to an area of low water concentration across a selectively permeable membrane.'
