Site of protein synthesis in cell is:
Correct answer: A. Ribosome
- A. Ribosome
- B. Endoplasmic reticulum
- C. Nucleolus
- D. Smooth endoplasmic reticulum
Explanation
The correct answer is Ribosome. Ribosomes are the cellular organelles where proteins are synthesized by translating messenger RNA (mRNA) into polypeptide chains. While the rough endoplasmic reticulum works closely with ribosomes in protein synthesis, it is not the primary site. The nucleolus, on the other hand, is responsible for making ribosomes, and the smooth endoplasmic reticulum is involved in lipid synthesis, not protein synthesis.

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.
