NEETBotanyPlant - Growth and Development
What is the initial phase of geometrical growth called?
Options
- ALog phase
- BExponential phase
- CLag phase
- DStationary phase
Correct answer
C. Lag phase
Step-by-step solution
In 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.
