Read the following Assertion and Reason and choose the correct option. Assertion: A sigmoid curve is typical for all cells, tissues and organs of a plant Reason: In a geometrical growth curve a typical sigmoid curve is achieved

Step-by-step solution

If we plot the parameter of growth against time, we get a typical sigmoid or S-curve (Figure 15.6). 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.
