Detailed explanation-1: -Q. If you looked at red blood cells under a microscope and saw the blood cells exploded, what would you say happened? The cells were placed in a hypotonic solution.
Detailed explanation-2: -Distilled water on the other hand is hypotonic to red blood cells. The red blood cell will therefore swell and haemoglobin, containing the haem that gives the red colour to erythrocytes, leaks from the cell resulting in a transparent red-pink-coloured solution.
Detailed explanation-3: -If placed in a hypotonic solution, a red blood cell will bloat up and may explode, while in a hypertonic solution, it will shrivel-making the cytoplasm dense and its contents concentrated-and may die. In the case of a plant cell, however, a hypotonic extracellular solution is actually ideal.
