Question
Match the following. When red blood cells are
placed in the three types of solution below, what will happen to the cell?Solution
A blood cell placed in a hypotonic solution would gain water as water will enter the cell from the surrounding hypotonic medium by the process of osmosis causing the cell to swell up. If the cell was placed in a hypertonic solution, water would have moved out of the cell causing it to shrink. Red blood cells do not have the cell wall and contractile vacuoles and hence, would not be able to maintain their shape leading to their rupture.
