It is possible to observe the plasmolysis of cells under the microscope when salt water is added to onion cells, then the cells will lose water due to osmosis, this can be observed. Osmosis the purpose of this lab is to study how membranes of plant and animal cells react when exposed to different solutions the first experiment involves purple onion skin and the second involves rat blood in various solutions. The phenomenon of plasmolysis is unlikely to occur naturally, and is typically induced in laboratory environments by immersing a plant cell into a strong saline or sucrose solution a common exhibit of plasmolysis is to place the outer tissue of an onion in a solution of calcium nitrate. Plasmolysis only occurs in extreme conditions and rarely happens in nature it is induced in the laboratory by immersing cells in strong saline or sugar solutions to cause exosmosis , often using elodea plants or onion epidermal cells .

Notice how the cell membrane detaches form the cell wall as the hypertonic solution (15% salty water) enters the cell. In this lab activity, you will create a wet mount of onion cell and expose it to a solution of salt to observe plasmolysis, as well as distilled water to see the reverse effect materials salt solution. Osmosis demonstration lab objectives observe plasmolysis in elodea background osmosis is the process whereby water moves across a cell membrane by diffusion. Plasmolysis purpose: the purpose of this lab experiment is to demonstrate a biological principle observed in plant cells called plasmolysis plasmolysis is the loss of water from the cell by osmosis, and this is evident when the cell contents pull away from the rigid cell wall as the water moves out.
