thing more than a magnifying glass with one lens, or with a compound microscope, which has two lenses at opposite ends of a tube. The ocular lens is the one nearest the eye, and the objective lens is nearest the object or specimen. Both of the microsco
pes that you will be using today are compound and quite a bit more sophisticated than the exquisite simple microscopes with which  Anton van Leeuwenhoek discovered the microbes.
 Microbes are organisms too small to be seen in any detail with the naked eye. They may be a single cell or they may contain many cells. Plants, animals, fungi, protests, and bacteria all include organisms that are microscopic in size.
\par How small are microbes? Actually, many can be detected with the naked eye if you know
