Here's why:

* Prokaryotes are single-celled organisms that lack a membrane-bound nucleus and other internal organelles. They are simple in structure, with their DNA located in a region called the nucleoid.

* Eukaryotes, on the other hand, are organisms whose cells have a nucleus and other membrane-bound organelles. This includes all plants, animals, fungi, and protists.

Examples of non-prokaryotes (eukaryotes):

* Humans

* Plants

* Mushrooms

* Algae

* Amoebas
