The correct option is B Q- Endoplasmic reticulum; R- Ribosomes
The endoplasmic reticulum is the network of the membranous tube-like structure. it serves many functions, including the folding of protein molecules in sacs called as cisternae and the transport of synthesized proteins in vesicles to the Golgi apparatus. It provides strength to cell cytoplasm. The ribosome is a large and complex molecular machine, found within all living cells, that serves as the site of biological protein synthesis (translation). Ribosomes link amino acids together in the order specified by messenger RNA (mRNA) molecules. The endoplasmic reticulum is studded with ribosome called as rough endoplasmic reticulum involves the formation, modification, and transportation of protein. Thus, the correct answer is option B.
