Prokaryotic cells do not have any organelles that are unique to them. This is because prokaryotes are simpler cells than eukaryotes and lack many of the complex organelles found in eukaryotic cells.

Here's a breakdown:

* Organelles in eukaryotic cells: These include the nucleus, mitochondria, Golgi apparatus, endoplasmic reticulum, lysosomes, and more.

* Organelles in prokaryotic cells: Prokaryotes have ribosomes, a cell membrane, cytoplasm, and a nucleoid region (where their DNA is located), but these structures are also found in eukaryotic cells.

The main difference lies in the organization and complexity of these structures. Prokaryotic cells lack the membrane-bound organelles found in eukaryotes, and their DNA is not enclosed within a nucleus.

Therefore, instead of unique organelles, prokaryotic cells have unique features like:

* A cell wall: Provides structural support and protection.

* Flagella: Tail-like structures used for movement.

* Pili: Hair-like structures used for attachment and conjugation.

* Capsules: A slimy layer that can protect against phagocytosis.

In essence, while prokaryotic cells have some unique features, they lack the specialized, membrane-bound organelles that define eukaryotic cells.
