Plasmolysis is the separation of plant cell cytoplasm from the cell wall as a result of water loss. It is unlikely to occur in nature, except in severe conditions. Plasmolysis is induced in the laboratory by immersing a plant cell in a strongly saline or sugary solution, so that water is lost by osmosis.

If onion epidermal tissue is immersed in a solution of calcium nitrate, cells rapidly lose water by osmosis and the protoplasm of the cells shrinks (Web Figure 3.8.A). This occurs because the calcium and nitrate ions freely permeate the cell wall and encounter the selectively permeable plasma membrane. The large vacuole in the center of the cell originally contains a dilute solution with much lower osmotic pressure than that of the calcium nitrate solution on the other side of the membrane. The vacuole thus loses water and becomes smaller. The space between the cell membrane and the cell wall enlarges and the plasma membrane and the protoplasm within it contract to the center of the cell. Strands of cytoplasm extend to the cell wall because of plasma membrane-cell wall attachment points. Plasmolysed cells die unless they are transferred quickly from the salt or sugar solution to water.

Can animal cells undergo plasmolysis?

Animal cells undergo lysis, and plant cells undergo plasmolysis. Lysis occurs when a plant cell explodes due to too much pressure on the inside, and plasmolysis occurs when the vacuole of a plant cell shrinks away from the cell wall due to lack of water.


What is the effect when you pour salt on a plant?

If the plant is not a salt water plant, then plasmolysis will occur when you pour salt on a plant.When you pour salt on a plant water molecules inside the cell are drawn out. When the water molecules leave the cell, the cell becomes dehydrates and shrinks. This is called plasmolysis.

What continent does not have tornadoes?

Antarctica is the continent that does not have tornadoes. Tornadoes typically form over land, so the cold and uninhabited nature of Antarctica makes it unlikely for tornadoes to occur there.

Why can't plasmolysıs take place in an animal cell?

Plasmolysis cannot occur in animal cells because they lack a rigid cell wall, which is essential for this process. Plasmolysis involves the contraction of the cell membrane away from the cell wall due to loss of water in a hypertonic environment. In animal cells, instead of plasmolysis, the cell would shrink and potentially undergo crenation when placed in a hypertonic solution, as there is no cell wall to provide structural support.
