what are the ports of an prokaryotic cell?

Question

and how do they function

Answer 1

I am not sure what you mean by the term "ports" can you clarify the question at all?  Thanks.

Answer 2

I'm going to assume you meant "parts," not "ports."

Prokaryotic cells can have different things, like cell walls, capsules, plasma membrane, ribosomes, cytoplasm, and DNA.

If you're JUST beginning your study of prokaryotic cells, then that should do for now. Look them up individually.
