Vedclass · Answer

(B) Ribosomes are the granular structures first observed under the electron microscope as dense particles by George Palade in $1953$. They are composed of ribonucleic acids $(RNA)$ and proteins and are not surrounded by any membrane.Eukaryotic ribosomes are $80S$ (where '$S$' stands for the sedimentation coefficient,Svedberg's unit),while prokaryotic ribosomes are $70S$.In eukaryotic cells,$70S$ ribosomes are also found within organelles such as chloroplasts and mitochondria,which supports the endosymbiotic theory of their origin.Therefore,$70S$ ribosomes are present in prokaryotic cells,as well as in the chloroplasts and mitochondria of eukaryotic cells.
