Multiple Choice
Osmosis is best defined as the movement of which of the following?
A
Water across a membrane from higher solute concentration to lower solute concentration
B
Water across a selectively permeable membrane from lower solute concentration to higher solute concentration
C
Water and solutes together across a membrane using ATP-driven transport proteins
D
Solute molecules across a selectively permeable membrane from higher solute concentration to lower solute concentration
Verified step by step guidance1
Understand the definition of osmosis: Osmosis is the passive movement of water molecules across a selectively permeable membrane.
Recognize the direction of water movement in osmosis: Water moves from an area of lower solute concentration (higher water concentration) to an area of higher solute concentration (lower water concentration).
Note that osmosis involves only water molecules, not solutes or other substances.
Distinguish osmosis from other transport processes: Osmosis does not require energy (ATP) and does not involve the movement of solutes.
Summarize that osmosis is specifically the movement of water across a selectively permeable membrane from lower solute concentration to higher solute concentration.
