Question
Describe the process of osmosis and its effect on cells when water levels are not controlled.
Answer
Osmosis is the movement of water molecules from an area of lower solute concentration to an area of higher solute concentration through a semi-permeable membrane. If water levels are not controlled, cells can either take in too much water, leading to swelling and potential bursting, or lose too much water, causing them to shrink and impair their function.
Explanation
This answer effectively describes osmosis and its consequences for cells, demonstrating the student's ability to apply knowledge of biological processes. The question tests both recall and application of the concept of osmosis in a biological context.
Common mistake
Misunderstanding Osmosis
Students often confuse osmosis with diffusion, thinking they are the same process.
Remember that osmosis specifically refers to the movement of water across a semi-permeable membrane, while diffusion involves the movement of solutes. Focus on how water levels must be balanced to prevent cells from swelling or shrinking.
