Question

From the below representation of growth phase, which is the missing growth phase?

(a) Exponential Growth Phase

(b) Final Lag Phase

(c) Initial Log Phase

(d) Final Log phase

This question was posed to me by my college director while I was bunking the class.

I would like to ask this question from Data Analysis in section Presentation and Analysis of Data of Bioprocess Engineering

Answer 1

Right option is (a) Exponential Growth Phase

For explanation I would say: The Log/ Exponential Growth phase is a period characterized by cell doubling. If growth is not limited, doubling will continue at a constant rate so both the number of cells and the rate of population increase doubles with each consecutive time period. For this type of exponential growth, plotting the natural logarithm of cell number against time produces a straight line.
