Multiple Choice
Which process does osmosis involve?
A
Movement of solute molecules through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration
B
Movement of solvent molecules through a semipermeable membrane from a region of higher solute concentration to a region of lower solute concentration
C
Movement of solvent molecules through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration
D
Movement of solute molecules through a semipermeable membrane from a region of higher solute concentration to a region of lower solute concentration
Verified step by step guidance
1
Understand the concept of osmosis: Osmosis is the movement of solvent molecules, typically water, through a semipermeable membrane.
Identify the direction of movement: In osmosis, solvent molecules move from a region of lower solute concentration to a region of higher solute concentration.
Recognize the role of the semipermeable membrane: The membrane allows only solvent molecules to pass through, not solute molecules.
Differentiate between solvent and solute: Solvent is the substance that dissolves the solute, and in biological systems, it is often water.
Apply the concept to the options given: The correct description of osmosis involves the movement of solvent molecules through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration.
