What term describes the stage in which bacteria do not grow or reproduce?

• A. Inactive stage
• B. Growth stage
• C. Reproductive stage
• D. Active stage

Answer: (A)

The concept tested here is recognizing a dormant state of bacteria, when they’re not growing or reproducing. In this phase, metabolic activity drops and cell division stops, allowing the organism to survive unfavorable conditions until the environment improves. That makes “inactive stage” the best fit, because it directly conveys that growth and reproduction aren’t occurring. The other terms imply activity—growth and reproduction suggest ongoing population increase, while active implies ongoing metabolism and division—so they don’t describe a non-growing, non-reproducing state.
