Ribosomes were discovered by:
Correct answer: D. Palade
- A. Golgi
- B. Porter
- C. De Robertis
- D. Palade
Explanation
Factual Recall. Ribosomes are minute, cellular and non-membranous particles having an average diameter of 23 mm (230 A°). In plant cells, ribosomes were first observed by Robinson and Brown (1953) in bean roots. In animal cells, these were discovered by Palade (1955), and are hence called Palade particles. Ribosomes form a part of fraction microsomes (made of broken ER, ribosomes and Golgi bodies)- a term given by A. Claude

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
