Since the levels of water inside the blood cell are lower than the levels outside the blood cell, water would diffuse down it's concentration gradient into the cell, and too much water in the cell would cause it too burst. This is known as lysis. The reason why this doesn't happen in blood is because the concentration in blood is lower than in pure water.
The cells swell and burst because of a cytolysis (osmotic lysis). This happens because the red blood cell is put into a hypotonic solution: distilled water. Due to the fact that the salt concentration is lower in water, it will try to equalize the concentration by forcing water into the red blood cell.
They swell because of abnormal concentration of osmotic pressure.
because red blood cells are blood and if they can disolve there for they will burt cause the blood has acid in it.
The cell wall is a semi-permeable membrane - water can diffuse in but the salts etc. inside, stop water diffusing out at the same rate.
the waters causes exocytosis meaning they cells are filled with water
The water enters the red blood cells by the process of osmosis and red blood cells becomes spherical and then burst.
Blood cells swell in hypotonic solutions
If a red blood cell is placed into a hypotonic solution then the water concentration inside the cell is lower than outside the cell. The salt concentration is higher inside the cell than outside. So, due to the process of osmosis (water will travel from an area of high concentration to an area of low concentration) and the water will enter the red blood cell, increasing the pressure inside the cells. Red blood cells only have a thin membrane, they therefore can not cope with this high pressure and will eventually burst.
Osmosis is a type of passive transport when a solution of higher concentration of something flows to an area of lower concentration. An animal cell has a certain percentage of water, and when it is placed in water (100% water) the water will automatically, through osmosis, flow into the cell. The cell cannot take this volume of water rushing in, and it ruptures.
Plasmolysis is the contraction of the protoplast of a plant cell due to water loss. Plasmoptysis on the other hand, is the rupture of the cell wall which causes the protoplasm to burst.
I think it has something to do with the fact that salt in a cell will make it burst, thus coaxing the splinter out.

3. water from the blood cell into its environment
If you put a cell in a hypotonic environment, such as a blood cell in water, it will swell up due to osmosis and lyse.
When a red blood cell is placed in distilled water it will swell and burst. This is a physical change.
The cell would swell and burst because of the osmotic pressure causes water to move into the cell.
The water vacuole would burst
A red blood cell placed in water will lyse or burst. The red blood cell is hypertonic in comparison to the pure water (hypotonic). Water will rush in to equalize the concentrations via osmosis, and the cell will lyse.
Water that is added would tend to equalize the amount of sodium and other substance inside the cell with what is outside the cell. Since the RBCs have more inside them, the pure water would move into the cell. This would cause the RBCs to swell and perhaps burst. The amount of water that is added to the blood would determined if the cells would burst. More pure water, the more likely the cell will burst.
simple diffusion. When you surround a cell with water the water diffuses through the cell membrane causing it to swell and burst. The opposite is hyper tonic.
both the cell will swell and rbc will burst easily while cells of onion peal will resist the bursting to some extenct
A red blood cell placed in a concentrated sugar solution will shrink and wrinkle. The red blood cell is hypotonic and the concentrated sugar solution is hypertonic. Water will rush out of the cell causing diffusion leading to the cell's shrinking.
Osmosis is taking place
Water passively moves from an area of high water concentration (the dilute water) to low water conc. (in cell) (i.e. down the water potential). This causes the cell to swell up and its contents to dilute. It eventually stops swelling when the water potential reaches zero i.e. when the tonicity of the environment = the tonicity inside the cell. If its membrane can't cope with the swelling it may eventually burst.
