If a solution surrounding a cell is hypertonic relative to the inside of the cell, how will water move? a. It will move into the cell via osmosis. b. It will move out of the cell via osmosis. c. It will not move, because equilibrium exists. d. It will evaporate from the cell surface more rapidly.

Hello everyone. And in today's video we have the following problem. So what will be a consequence if a cell is placed in a hypothalamic solution? I want you to recall from previous videos what a hype atomic solution is and in case you've forgotten, let me just quickly remind you of what it is. So here we have it. Hypothalamic solution is a solution that contains a solid concentration that is higher inside of the cell. Now because of osmosis, water will go into the areas that high, higher salt concentrations. So water will go into the cell which will cause the cell to swap. Now let's go over answer choices so that we can solve this problem. So starting by answer choice A the water will leave the cell and the cell will die. It is incorrect because as we see here water goes into the cell. So let's cancel that out the cell wall for answer choice B The cell wall will be too concentrated because in some organelles to malfunction. This is actually incorrect as well because that does not have anything to do with what we're seeing here in this process of placing a cell in a hypothermic solution. So we're going to cancel it out. Then we have the solar concentration will be equal inside and outside the cell. If this was true, then we would have an isotonic solution which is what we see here. We have same concentrations of water and solute in and outside of the cell and this all lips as we actually see the water will enter the cell. So it goes into the cell and cause it to swell as we saw here and burst eventually. It is actually the process that will be happening if we place the cell in a high platonic solution, so we're going to highlight as the final answer. I really hope this video helped you and I hope to see you on the next one.
