The information as stated is false.

<h3>What is a microscope?</h3>

A microscope is a device that could be used to view the interior of a cell. It is a device that uses light to show the interior of the cell. The magnification of the microscope is what determines how much information that you could get from it.

Thus, it is false to say that viewing the shape of a bacterial or archaeal cell using a microscope gives a great deal of information about the metabolism and lifestyle of the organism.
