Which of the following graphs illustrates the population growth curve of single bacterium growing in a flask of ideal medium at optimum temperature over a 24-hour period?

Question

Quizplus · Accepted Answer

The graph in option C shows the typical sigmoid (S-shaped) curve of bacterial growth. The lag phase (initial slow growth), exponential phase (rapid growth), and stationary phase (population stabilization) are all clearly visible. The decline in population in the death phase is not visible as the time period is limited to 24 hours. The graphs in options A, B, D, and E do not show the typical sigmoid curve of bacterial growth.
