Here's why:
* Prokaryotic cells are simple, single-celled organisms like bacteria and archaea.
* They lack a true nucleus, meaning their genetic material (DNA) is not enclosed within a membrane. Instead, it exists as a single, circular chromosome located in a region called the nucleoid.
* They also lack other membrane-bound organelles, such as mitochondria, Golgi apparatus, endoplasmic reticulum, etc.
Eukaryotic cells, on the other hand, are more complex cells found in plants, animals, fungi, and protists. They have a true nucleus and a variety of membrane-bound organelles.
