Question

For bacterial growth in a cell culture, growth law is very similar to the law of radioactive decay. Which of the following graphs is most suitable to represent bacterial colony growth? Where \( N \) - Number of Bacteria at any time, \( N_0 \) - Initial number of Bacteria.

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

For bacterial growth, use exponential growth models, which show a rapid increase initially followed by leveling off as resources become limiting.

Answer 1

The Correct Option is A

Bacterial growth in a culture follows exponential growth, which can be modeled similarly to radioactive decay. The graph that best represents this growth is the one that shows exponential increase over time.
