NEETBotanyPlant - Growth and Development
During which phase does the growth increase rapidly at an exponential rate in geometrical growth?
Options
- ALag phase
- BExponential phase
- CStationary phase
- DDecline phase
Correct answer
B. Exponential phase
Step-by-step solution
I n most systems, the initial growth is slow (lag phase), and it increases rapidly thereafter – at an exponential rate (log or exponential phase). Here, both the progeny cells following mitotic cell division retain the ability to divide and continue to do so.However, with limited nutrient supply, the growth slows down leading to a stationary phase. If we plot the parameter of growth against time, we get a typical sigmoid or S-curve.
