Question

The process of growth is maximum during:

• A. Senescence
• B. Dormancy
• C. Log phase
• D. Lag phase

Answer 1

The correct option is C Log phase

An idealised process of growth is divided into three phase - lag phase, log phase and stationary phase.

• Lag phase: This is the initial phase where there is no or little growth.
• Log phase: Lag phase is followed by log phase where the process of growth is maximum (exponential).
• Stationary phase: In this, the net growth rate remains stationary due to equal rate of growth and death.

Senescence: It is the gradual declining of growth in an organism.

Dormancy: It is a period in an organism when growth and development are temporarily suspended.
