Here's why:
* Prokaryotes are simple, single-celled organisms that lack a membrane-bound nucleus and other membrane-bound organelles. Their genetic material (DNA) is located in a region called the nucleoid, but it's not enclosed within a membrane.
* Eukaryotes, on the other hand, are more complex organisms that have a true nucleus containing their DNA, as well as other membrane-bound organelles.
Examples of prokaryotes include bacteria and archaea.
