Growth rates determine how life procedes, and some living things reach great age while others expire after a brief existance.
Microorganisms are everywhere and are competing with one another.
Their relative growth rates determine which ones win out and achieve predominance. There are many industrial uses of microorganisms. Because time is related to costs, it is usually much more economic to conduct your process more rapidly, and this means faster growth. This exercise takes you through some experiments on the doubling time of bacteria. Although bacteria can be spheres, elongated spheres, rods with rounded ends, or spirals, our computer program shows them as circles that stand for spheres.
