Step 2:: Understand the Key Concept of Isotonic Solution
An isotonic solution is a solution that has the same solute concentration as the cell's internal environment. This means the concentration of solutes is equal both inside and outside the cell membrane.
Step 3:: Analyze the Cellular Response
When a cell is placed in an isotonic solution: - The solute concentration is the same inside and outside the cell - There is no net movement of water across the cell membrane - The cell maintains its original size and shape
Step 4:: Determine the Correct Answer
Since the solution states that a cell will not swell or shrink in an isotonic solution, this is a TRUE statement.
Step 5:: Explain the Reasoning
In an isotonic solution: - No osmotic pressure exists - Water molecules move equally in both directions across the membrane - The cell's volume remains constant
Final Answer
True The statement is correct because in an isotonic solution, the cell experiences no net water movement, thus maintaining its original size and shape.
