Question

Choose the correct name of phases A, B and C in the given figure:

Options

• Stationary, Log, Lag 

• Log, Lag, Stationary

• Log, Stationary, Lag

• Lag, Log, Stationary

Answer 1

Lag, Log, Stationary

Explanation:

1. Lag Phase (A) – In this initial phase, microorganisms adjust to the new environment, and there is little to no growth as they prepare for cell division.

2. Log Phase (B) – Also called the exponential phase, where microorganisms multiply rapidly at a constant rate due to favorable conditions.

3. Stationary Phase (C) – Growth slows down and stabilizes as nutrients deplete and waste accumulates, leading to an equal rate of cell division and death.
