Select the incorrect statement among the following.

Options

A. Increase in growth per unit time is growth rate.
B. A sigmoid growth curve is a characteristic of most living organsims in their natural environment.
C. Rate of growth is constant during geometrical growth.
D. Exponential phase is also called as log phase.

Answer

C

Explanation

Geometric growth is quite common in unicellular organisms when grown in nutrient rich medium. Here, every cell divides. The daughter cells grow and divide, the grand daughter cells repat the process and so on. Number of cells is initially small so that growth is slow. later on, there is rapid growth at exponential rate (log or exponential growth).
