Ribosomes are tiny Granules first studied in 1955 by__________?
Correct answer: D. Palade
- A. De-Duve
- B. Schwann
- C. August Weismann
- D. Palade
Explanation
George Emil Palade first studied ribosomes using electron microscopy and described them as small cytoplasmic granules in 1955. Schwann is associated with cell theory, so students may select him by confusing a general cell-biology contribution with the discovery of ribosomes.

About Cytoplasmic Organelles
Cytoplasmic organelles are the specialized structures suspended in cytoplasm, including mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles and centrosomes. Questions compare their structures and functions in animal and plant cells, including chloroplasts and the role of the endomembrane system in transport and secretion.
