Detailed explanation-1: -In hypotonic solutions, there is a net movement of water from the solution into the body. A cell placed into a hypotonic solution will swell and expand until it eventually burst through a process known as cytolysis.
Detailed explanation-2: -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.
Detailed explanation-3: -A blood cell placed in hypotonic solution would gain water as water will enter cell from surrounding hypotonic medium by the process of osmosis causing the cell to swell up. If the cell was placed in hypertonic solution, water would have moved out of the cell causing it to shrink.
Detailed explanation-4: -When a cell placed in hypertonic solution (has more solutes that cell), the cell will shrink because water moves out, firstly from the cytoplasm and then from the vacuole. This process is called as exosmosis which leads to the plasmolysis.
Detailed explanation-5: -When a red blood cell is placed in a hypertonic solution, it shrinks as water is drawn out of the cell and into the surrounding solution. If the same blood cellis placed in a hypotonic solution, the blood cell grows in size. Blood cells in isotonic solutions do not shrink or swell.
