Question

Which is the correct sequence or order for the four phases of bacteria growth?

Answers

  1. Stationary, lag, log, and death.
    • Rationale:

      This is not the sequential order for the phases of bacterial growth.

  2. Stationary, log, lag, and death.
    • Rationale:

      This is not the sequential order for the phases of bacterial growth.

  3. Log, lag, stationary, and death.
    • Rationale:

      This is not the sequential order for the phases of bacterial growth.

  4. Lag, log, stationary, and death.
    • Rationale:

      This is the sequential order for bacterial growth. The order is the lag phase, the log phase, the stationary phase, and the death phase.

Overview

Bacteria is a member of a large group of unicellular microorganisms. These microorganisms have cell walls but lack organelles and an organized nucleus.

Explanation

Learning Outcomes

Bacterial growth is the proliferation of bacteria. There are four phases of bacterial growth. The phases, in sequential order, include the lag phase, the log phase, the stationary phase and the death phase.

Test Taking Tip

Sequential indicates that the correct answer must be in the order in which bacterial growth occurs.
