During which stage do bacteria primarily increase in number?

• A. Inactive stage
• B. Active stage
• C. Dormant stage
• D. Resting stage

Answer: (B)

The active stage is when bacteria primarily increase in number. During this phase, bacteria are metabolically active and engage in processes such as cell division, which leads to exponential growth. This stage is characterized by favorable environmental conditions, such as adequate nutrients, optimal temperature, and suitable pH, all contributing to rapid reproduction. In contrast, the inactive and dormant stages represent periods of reduced activity or survival rather than growth. During these stages, bacteria may exhibit minimal metabolic function and not divide, thereby preventing an increase in population. The resting stage also indicates a lack of significant reproduction, as the focus shifts to survival mechanisms. Thus, the active stage is critical for understanding bacterial growth dynamics and is essential for maintaining effective sanitation and control measures in food safety and public health.
