Answer: e. generation time
Explanation:
The generation time is the time that is required by the bacterial cell or cell of the any other organism required to be doubled in number during a specified or constant period of time. The generation time can vary in different organisms.
For example, the E.coli cell divides in every 20 minutes, hence, the generation time of the E.coli is 20 minutes and for the Staphylococcus aureus it is seen as 30 minutes.
Generation time refers to the duration required for a cell to duplicate a population of microbial cells, Bacteria divide at this constant time interval.
It is the time required for two cells to form from one cell, this varies widely among microorganisms due to environmental conditions such as temperature.
Many bacteria have generation times of 1-3 hours, but fast-growing ones can do so in 10 minutes, while others can take days.
Therefore, we can conclude that generation time refers to the constant time it takes for a microbial population to double, Bacteria divide at this constant time interval.
