Ribosomes are non-membranous cell organelles that are present in both prokaryotic and eukaryotic cells. In prokaryotes they are of the 70S type while in the eukaryotes they are of the 80S type. A ribosome consists of a larger and a smaller unit. Each unit is made of rRNA and proteins.
So, the correct answer is 'Ribosome'
