Question

Long Answer Question:

Explain sigmoid growth curve with the help of diagram.

Answer 1

1. The curve obtained when a graph of growth rate against time is plotted for three phases of growth is called as a sigmoid curve.

2. Growth rate differs with three distinct phases of growth.

3. In the Lag phase, the growth rate is slow.

4. In Exponential (Log) phase, growth rate is faster and reaches its maximum.

5. In Stationary phase, growth rate gradually slows down.
