Explain the effect what solutions on living cells hypertonic?

Answer 1

An isotonic solution means that the water potential of the solution is the same of that of the cells, so no osmosis should occur, which is why many experiements are necessary to occur in an isotonic solution. however if solutions are NOT isotonic, cells are affected. if the solution has a more negative water potential (stronger sugar concentration outside the cells than inside the cells) then water will leave the cells to try to even the water potentials. If an animal cell, the cell will shrivel up and if it is a plant cell, the cell membrane will shrivel up but the cell will keep its structure because of its cell wall. if the solution has a more positive water potential then water will enter the cell. If too much water enters the cell, then in an animal cell the cell will burst - lysis - and in a plant cell, a series of events will happen. First the cell membrane will expand until it bursts like in the animal cell. However there is still a cell wall but this is but semi-permable so fluids freeloy move pass it. The outside solution will fill into what is left of the cell. This is called plasmolysis. nice

Answer 2

Hypotonic means that the solution has less solutes than the cell. This means that there will be a net flow of water into the cell (in order to try to reach equilibrium). An animal cell placed in a hypotonic solution will eventually burst (depending on how different the solute concentrations are).

Answer 3

Hypertonic solutions will cause cells to become dehydrated, which will cause them to shrivel. Hypotonic solutions will cause cells to swell and even burst. Isotonic solutions will have no impact on living cells, provided they are not poisonous.

Answer 4

Water from the surrounding solution moves osmotically into the cell and swells it.

Answer 5

This causes the water within the cell to move osmotically from the interior of the cell to the surrounding solution. Cell crenelation.

Answer 6

The cell will swell as more water will enter in the cell.

Answer 7

Hypertonic solution causes exosmosis from cell which results in shrinkage and crenulation of animal cell and plasmolysis in plant cell .
