"Ribosomes in the cytoplasm of prokaryotic and eukaryotic cells slightly differ. Prokaryotic ribosomes are smaller and less dense and each contain only three strands of RNA and about fifty proteins. Eukaryotic ribosomes consist of four strands of RNA and contain seventy to eighty proteins. The ribosomes in mitochondria and chloroplasts resemble prokaryotic ribosomes."
