Plasmolysis (Plasmolysis)

Plasmolysis is a process that occurs in the cells of bacteria and plants, during which protoplasm peels off from the dense cell wall. This process is observed when the cell is placed in a hypertonic solution, i.e. a solution with a higher concentration of dissolved substances compared to cell sap.

Plasmolysis occurs due to the fact that water leaves the cell into the surrounding solution according to the laws of osmosis. The concentration of solutes inside the cell is lower than outside, so water diffuses out. As a result, the volume of the cytoplasm decreases and it peels off from the cell wall.

Thus, plasmolysis is an important process that allows the cell to maintain osmotic pressure and water-salt balance. It occurs due to the phenomenon of osmosis and the diffusion of water from the cell when it is placed in a hypertonic solution.

Plasmolysis is a process that occurs in bacterial and plant cells, which consists of the peeling of protoplasm (the liquid part of the cell) from the dense cell membrane when the cell is placed in a solution with a higher concentration of solutes. This process results from the removal of water from cells due to osmotic pressure.

Under conditions of a hypertonic solution, the concentration of solutes in it is higher than in the cell, which leads to the fact that water begins to move from the cell to the environment. This causes the protoplasm to peel off from the cell membrane, which manifests itself in a change in the shape and size of the cell.

Plasmolysis plays an important role in the life of bacteria and plants. It helps them adapt to changing environmental conditions, such as changes in solute concentrations or changes in temperature. In addition, plasmolysis can be used to obtain nutrients from plant tissues. For example, when producing juices from fruits and vegetables, plant cells undergo plasmolysis, which allows more nutrients to be extracted from the plant.

However, plasmolysis can also be dangerous for living organisms. If a cell undergoes plasmolysis under conditions where it cannot adapt to new conditions, this can lead to its death. Therefore, in order to avoid plasmolysis, it is necessary to control the concentration of solutes and the ambient temperature.

Plasmolis - This word is of ancient Greek origin "plasmos" and means plasma. In a general sense, plasmolysis is the process of leaving cells of most of their contents. A plasmolytic response can also be obtained in solutions of various substances. Even if the system with the test substance has the osmotic potential for a small amount of solvent to penetrate into the cell, it will swell and deform until its wall ruptures. This phenomenon is called plasmolysis. Externally, this process looks like the removal of parts of cellular structures in the form of bubbles or the flow and penetration of a solvent through the cell membrane. In this case, the cell wall can be destroyed from the inside.
