      If cells of onion peel and RBC are separately kept in hypotonic solution, what will happen to each of them? Explain.   [NCERT Exemplar]

    Answer:

                    When kept in a hypotonic solution, the onion cells will become turgid because the water will enter the cell due to osmosis. But the cell wall present outside the cell provides it rigidity and does not let any harm to occur. Whereas, in RBC the movement of water inside the cell due to osmosis will lead to bursting of the cell because it does not have a rigid cell wall.
