Here's a breakdown:

* Ribosomes are complex molecular machines found in all living cells.

* They are responsible for translating the genetic code carried by messenger RNA (mRNA) into a chain of amino acids, which then folds into a functional protein.

* Ribosomes can be found free-floating in the cytoplasm or attached to the endoplasmic reticulum (ER).
