Cytolysis

The presence of a cell wall prevents the membrane from bursting, so cytolysis only occurs in animal and protozoa cells which do not have cell walls.

A major function is to act as pressure vessels, preventing over-expansion of the cell when water enters.

The reverse process is plasmolysis.

The reverse process, deplasmolysis or cytolysis, can occur if the cell is in a hypotonic solution resulting in a lower external osmotic pressure and a net flow of water into the cell.

It occurs in a hypotonic environment, where water moves into the cell by osmosis and causes its volume to increase to the point where the volume exceeds the membrane's capacity and the cell bursts.

For cells without a cell wall such as animal cells, if the gradient is large enough, the uptake of excess water can produce enough pressure to induce cytolysis, or rupturing of the cell.

In animal cells excessive osmotic pressure can result in cytolysis.

Cytolysis, or osmotic lysis, occurs when a cell bursts due to an osmotic imbalance that has caused excess water to diffuse into the cell.

Osmotic lysis is often one result of a stroke, because of improper nutrient perfusion and waste removal alter cell metabolism.

Such malfunction results in an inflow of extracellular fluid into the cells.

Osmotic lysis would be expected to occur when bacterial cells are treated with a hypotonic solution with added lysozyme, which destroys the bacteria's cell walls.

For example, the paramecium uses a contractile vacuole, which rapidly pumps out excessive water to prevent the build-up of water and the otherwise subsequent lysis.

Other organisms pump solutes out of their cytosol, which brings the solute concentration closer to that of their environment.
