Viewing the
microbial world
A Lesson in the Metric System & Microscopy
,What we’ll learn after this:
To explain the interrelationships among the
following metric system units of length:
centimeters, millimeters, micrometers, and
nanometers;
To state the metric units used to express the size
of bacteria, protozoa, and viruses; and
To compare and contrast the various types of
microscopes, to include simple microscopes,
compound light microscopes, electron
microscopes, and atomic force microscopes.
, Using the Metric System to
Express the Sizes of Microbes
In microbiology, metric units are used to express the sizes
microbes.
A system of measurement that
succeeded the decimalized
system based on the meter
introduced in France in the
1790s.
, Using the Metric System to
Express the Sizes of Microbes
The meter was originally defined to be one ten millionth of th
distance between the North Pole and the Equator through Par
Today, a meter
distance travele
light in 1/300,00
of a second
vacuum.
