Ribosome is composed of protein and RNA and is used to make proteins for the cell and is a common structure between prokaryotes and eukaryotes.

Explanation:

Ribosome in Prokaryotes has 2 subunits of 50S and 30S. They are composed of rRNA. It is in ribosome the protein synthesis of prokaryotes takes place. The ribosome in prokaryotes float free in the cytosol.

Ribosome in eukaryotes is larger and has 2 subunits of 60S and 40S. Ribosome is made up of ribonucleoproteins. They synthesize proteins based on the information from mRNA. The ribosome in eukaryotes is membrane-bound.
