Question

The figure of Sigmoid growth curve given below, label segments 1, 2 and 3.

Answer 1

Sigmoid growth curve:

The sigmoid growth curve has three prominent phases:

• Initial lag phase: Slower development due to fewer cells introduced into a set of conditions.
• Rapid exponential phase: Fast development due to abundant resources and minimal environmental resistance.
• Gradual stationary phase: Onset of unfavorable conditions like gradual exhaustion of nutrients cause decline in growth.

Final answer:

1. Lag phase
2. Log phase/ exponential phase
3. Stationary phase
