Here's a breakdown:

* Ribosomes: These are complex molecular machines found in all living cells. They are responsible for translating the genetic code from messenger RNA (mRNA) into proteins.

* Prokaryotic ribosomes: These are smaller and structurally different from eukaryotic ribosomes. They consist of two subunits: a 30S subunit and a 50S subunit, which combine to form a 70S ribosome.

So, while prokaryotes lack many of the organelles found in eukaryotic cells, they still have the essential machinery needed for protein synthesis – the ribosomes.
