What are limiting, incipient, evident plasmolysis? Give differences between them. Explain
Plasmolysis is defined as the process of contraction or shrinkage of the protoplasm of a plant cell and is caused due to the loss of water in the cell. Plasmolysis is an example of the results of osmosis and rarely occurs in nature. The word Plasmolysis was generally derived from the Latin and Greek word plasma – The mold and lysis meaning loosening.
Stages of Plasmolysis-
The complete process of Plasmolysis take place in three different stages:
Incipient plasmolysis: It is the initial stage of the plasmolysis, during which, water starts flowing out of the cell; initially, the cell shrinks in volume, and the cell wall becomes detectable.
Evident plasmolysis: It is the next stage of the plasmolysis, during which, the cell wall has reached its limit of contraction and cytoplasm gets detached from the cell wall attaining the spherical shape.
Final plasmolysis: It is the third and final stage of the plasmolysis, during which the cytoplasm will be completely free from the cell wall and remains in the center of the cell.
