Q
The Growth Curve
A
Cell division increases the number of cells in a
population
•
Population growth is studied by analysing the
growth curve
•
In liquid medium cells are cultured in a closed system or batch culture with no new
fresh medium. Over time:
•
nutrient concentrations decline
•
waste components increase
•
The growth of organisms dividing by binary fission is plotted as the logarithm of the
number of viable cells versus incubation time
