Here's a bit more information:

* Prokaryotes are single-celled organisms that lack a nucleus and other membrane-bound organelles. They are the simplest and most ancient forms of life on Earth.

* Eukaryotes, on the other hand, are organisms made up of eukaryotic cells, which have a nucleus and other membrane-bound organelles.

* The two main types of prokaryotes are bacteria and archaea.
