In this module, you learned that some bacteria can grow
at alarming rates. Now, you
will track the growth of a single cell for a short period of time. For this exercise, let’s assume that bacteria divide every
8 minutes, a rate that is sometimes found in the natural environment.
But first, remember how bacteria grow…one cell becomes two, two
becomes four, four becomes eight, etc.
Start by using the table in the response sheet to track the
progress of the bacterial colony over two hours, or 120 minutes.
Remember these bacteria
double every 8 minutes!
Use the data accumulated in your response sheet's table to plot the
growth on the Q/A Response worksheet.
Next, use the graph and your knowledge of ecology to answer the
questions on the Q/A Response worksheet.
