A red blood cell is placed in a salt solution that is much more concentrated than its cytoplasm. What happens to the cell?
Answer and explanation
Correct answer: D. It shrinks
- Step 1: The solution outside the cell has a lower water potential than the cytoplasm. Step 2. Water leaves the cell by osmosis, so the cell shrinks. Answer: It shrinks. Why not the others: Swelling and bursting happen in a solution more dilute than the cytoplasm, no change happens in a solution of equal concentration, and red blood cells have no nucleus and do not divide.
