plasmolysis

This term describes a specific physiological collapse within plant or bacterial cells. It evokes an image of internal shrinkage and detachment, where the living content of the cell pulls away from its rigid outer boundary due to osmotic pressure. It is used almost exclusively in biological and botanical academic contexts to describe cellular dehydration.

As a technical mass noun, plasmolysis is uncountable. It refers to a biological process rather than a discrete object, meaning it does not have a plural form and cannot be counted with numbers. To refer to individual instances of the process, one must use partitive phrases such as a case of plasmolysis.
