As a result it will cause plasmolysis which is the process of shrinkage of the cell as a result of loss of water from the protoplasm to the environment.

In the present study it is proposed that the extracts caused membrane damage during the one hour of incubation by increasing the membrane permeability and this caused the decrease in absorbance since plasmolysis did not occur when the cells were placed in PBS containing NaCl.
As the salt concentration increased further (hypertonic), the process was reversed which resulted in further plasmolysis of the green pepper cells, thereby drastically reducing its moisture content, hence, reduced drained weight.
