Where are ribosomes located in eukaryotic cells?

Answer is: On the rough endoplasmic reticulum and in the cytoplasm.

Explanation:

A ribosome is made up of RNA and protein and is used as the site for protein synthesis within all living cells.

Ribosomes found free floating in the cytoplasm or they are bound to the endoplasmic reticulum.

If they bound to Endoplasmic Reticulum then they are known as rough endoplasmic reticulum. If they do not bound to Endoplasmic Reticulum then Endoplasmic Reticulum is smooth and thus known as smooth ER.

In Eukaryotes, there are membrane bound organelles and thus ribosomes can be found free floating in cytoplasm or can bound to endoplasmic reticulum called as RER.

In prokaryotes, membrane-bound organelles are not present and thus ribosomes are found only free floating in the cytoplasm.
