prokaryotes
The cell types in Bacteria and Archaea are considered “prokaryotes.” The use of the term prokaryote was first introduced as a result of electron microscope studies showing a shared simple cell structure among bacteria (Stanier & Van Niel 1962).
Bacteria are classified as prokaryotes, along with another group of single-celled organisms, the archaea. Prokaryotes are tiny, but in a very real sense, they dominate the Earth. They live nearly everywhere – on every surface, on land and in water, and even inside our bodies.
