Which of the following phases of the bacterial growth curve is matched with the correct definition?
a. lag phase--the phase in which the death of organisms exceeds the creation of new cells and the curve declines
b. stationary phase--the phase in which cells are not dividing very rapidly as they acclimatize to a new environment
c. log phase--the phase in which organisms are actively dividing and the generation time is constant
d. death phase--the phase in which the curve is flat; microbial deaths balance the number of new cells

Option-C

Explanation:

When the bacteria are grown artificially in the selected growth medium, the bacterial growth cycle can be plotted on the graph which is divided into four phases namely lag phase, log phase, stationary and death phase.

In the given question, the description of the phase is provided in which only the description of the log phase matches or is correct.

The log phase is the exponential phase which represents the growth of the bacteria in exponential therefore the generation time is constant and the bacteria actively divides.

Thus, Option-C is correct.
