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, N₀ - Initial number of Bacteria.

Accepted Answer

(C) N/N₀ vs time: starts at a positive value and rises ever more steeply (exponential growth)

Answer

(A) N/N₀ vs time: rises steeply from the origin and levels off (saturating curve)

Answer

(B) N/N₀ vs time: decreasing exponential (decay curve)

Answer

(D) N/N₀ vs time: straight line decreasing
