Bacterial growth curve
In higher organism growth refers as increase in size and volume of organism but in bacteria growth refers as increase in number.
When fresh liquid medium is inoculated with a given number of bacteria and incubated for sufficient period of time, it gives a characteristic growth pattern of bacteria.
If the bacterial population is measured periodically and log of number of viable bacteria is plotted in a graph against time, it gives a characteristic growth curve which is known as growth curve or growth cycle.
The growth curve is hyperbolic due to exponential bacterial growth pattern.
