Growth curve is
Growth curve is
Open in App
Solution
The correct option is D Both (A) and (B)
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. A sigmoid curve is a characteristic of living organism growing in a natural environment. It is typical for all cells, tissues and organs of a plant.Thus, the correct answer is option D.
