Which of the following best describes osmosis?
A
The movement of solute molecules from an area of high concentration to an area of low concentration through a membrane.
B
The active transport of ions against their concentration gradient using energy.
C
The bulk movement of substances into a cell by engulfing them in vesicles.
D
The movement of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.
Verified step by step guidance1
Step 1: Begin by understanding the concept of osmosis. Osmosis is a type of passive transport that involves the movement of water molecules across a selectively permeable membrane.
Step 2: Recognize that osmosis occurs due to differences in solute concentration on either side of the membrane. Water moves from an area of low solute concentration (high water concentration) to an area of high solute concentration (low water concentration).
Step 3: Note that osmosis does not involve the movement of solute molecules, active transport, or bulk transport. It specifically refers to the movement of water molecules.
Step 4: Understand the role of the selectively permeable membrane. This membrane allows water to pass through while restricting the movement of solute molecules.
Step 5: Confirm that the correct description of osmosis is: 'The movement of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.'
