hypertonic solution
Solution causes a cell to swell by osmosis
Osmosis is taking place
The chemical concentration inside the cell is greater than outside therefore water moves by osmosis into the swell and causes it to swell. If this continues beyond a certain point the cell can lyse (burst).
Any solution with more H2O than inside the cell will cause the cell to swell. Animal cells will burst under a lot of pressure, but plant cells will not, due to the presence of a cell well surrounding the cell. In other words, a hypotonic solution will cause a cell to swell, and a hypertonic solution will cause a cell to shrink. Hypo -> hyper
It softens and causes the hair to swell
water enters a cell by osmosis, causing the cell to swell.
A hypotonic solution will make a cell swell. When the environment is hypotonic to the contents of the cell, it will take on water and swell. When a cell is in a hypertonic solution, it will lose water and shrivel up and/or shrink. When a cell is placed in a isotonic solution, the cell is equal and the same. It will not swell nor shrink. Both hypotonic and hypertonic solutions can kill the cell.
Red blood cells that are put in a dilute salt solution swell because of osmosis. This process causes red blood cells to swell in hypotonic solutions because the liquid tries to dilute the cells' solution since it tries to equalize the solution's tonicities.
Osmosis is the movement of water from a High Water (Dilute Solution) to a Low Water (Strong Solution). If blood plasma becomes very dilute with water, when it travels to the brain the brain cells will swell because the are taking on too much water. This happens because the high concentration of water (in the blood) is moving to the lower concentration of water (brain cells) making the cells swell as they are taking on too much water.
osmosis!
If cells are placed in a hypotonic solution the cells gain water. The hypotonic solution has lower solute concentration then the cell's cytoplasm so the water will enter via osmosis.
When a plant cell is placed in an hypotonic solution it becomes swollen and hard. The cell takes in water by osmosis and starts to swell, but the cell wall prevents it from bursting.
