Question

Microbial growth is the result of both cell division and change in cell size.

(a) True

(b) False

I got this question in my homework.

This intriguing question comes from Cell Growth Kinetics topic in section Homogenous Reactions of Bioprocess Engineering

Answer 1

The correct option is (a) True

Explanation: Growth for multicelluar organisms is typically measured in terms of the increase in size of a single organism, microbial growth is measured by the increase in population, either by measuring the increase in cell number or the increase in overall mass. Cell division process begins with cell elongation, which requires careful enlargement of the cell membrane and the cell wall, in addition to an increase in cell volume.
