Question

what is growth and mention the stages of growth

Answer 1

Growth is an irreversible permanent increase in size, volume and weight of an organ or its parts or even of an individual cell.
Stages of growth are:
1. Lag phase: initial phase of growth when the rate of growth is very slow.
2. Log phase: Growth progresses rapidly or exponentially i.e. , reaches to its maximum.
3. Stationary phase: Due to shortage of space, food and accumulation of toxins, growth slows down leading to this phase.
