Verified by Experts

The correct Answer is:
A
Ribosomes are granular structures which were discovered by Robinson and Brown (1953) in plant cell and by palade (1955) in animal cell. Palade (1955) also coined the term ribosomes hence, they are also called palade particles. Ribosomes occur in both prokaryotic and eukaryotic cells.
