Question

The first phase of a growth curve is:

• A. Log phase
• B. Lag phase
• C. Stationary phase
• D. Decline phase

Hint:

In biological growth curves, the lag phase marks the period where cells adjust to the new environment before they start rapid division and growth.

Answer 1

The Correct Option is B

The first phase of a growth curve is the Lag phase. This is the initial phase where the organism or cells are adapting to their environment and there is no significant increase in growth. The cells are metabolically active but not yet dividing at a rapid rate. Following the lag phase, the Log phase occurs, where growth accelerates as cells begin to divide rapidly.
