Multiple Choice
Which of the following statements is true regarding osmosis?
A
Osmosis is the movement of water molecules from a region of higher solute concentration to a region of lower solute concentration.
B
Osmosis requires energy input to occur.
C
Osmosis can occur in any type of solution, regardless of the presence of a semipermeable membrane.
D
Osmosis is the movement of water molecules through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration.
Verified step by step guidance
1
Understand the concept of osmosis: Osmosis is a type of passive transport, which means it does not require energy input. It involves the movement of water molecules across a semipermeable membrane.
Identify the direction of water movement in osmosis: Water molecules move from an area of lower solute concentration to an area of higher solute concentration. This is because water moves to balance the concentration of solutes on both sides of the membrane.
Recognize the role of the semipermeable membrane: A semipermeable membrane allows only certain molecules, like water, to pass through while blocking others, such as solute particles. This is crucial for osmosis to occur.
Evaluate the given statements: Compare each statement with the correct definition of osmosis. The first statement incorrectly describes the direction of water movement. The second statement incorrectly states that energy is required. The third statement ignores the necessity of a semipermeable membrane.
Conclude with the correct statement: The correct understanding of osmosis is that it is the movement of water molecules through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration.
