The physiology of stationary-phase cells depends on what caused the cessation of growth.
Option: (a)
Explanation:
In the physiology of stationary phase the cells then becomes spherical and later it transforms into smaller rigid cell envelop.
The walls surrounded by the cell wall are highly crossed-linked, next the 'fluidity of the membrane reduces gradually', and there is a response given by the stringent response mechanism.
The response is given for a certain purpose in order to survive the calamity.
