Answer: Time required for a population to double
Explanation: The basic definition of generation time is "the time interval between two successive generations" is known as generation time.
[Note: The log phase is known as exponential phase. Log phase also can be considered as generation time technically. It is the most active phase. It is the period inwhich cell division occurs exponentially and biomass increases in the culture.]

3) Use the logarithmic phase of the growth curve to estimate the generation time (g units are hours/generation; also known as the doubling time) of E. coli. How does the generation time that you estimated compare to the published generation times for E. coli growing under optimal conditions? What are some of the possible reasons for differences in the generation times? What are possible sources of error in this exercise?
