The rough endoplasmic reticulum is specially well developed in cell actively engaged in

• A. Protein synthesis
• B. Nucleotide synthesis
• C. Lipid synthesis
• D. Secretory functions

Answer 1

The correct option is A Protein synthesis

Endoplasmic reticulum (ER) is a tube-like structure present in the cell, which extends all over the cell. It is of two types rough (with ribosome) and smooth (without ribosome) endoplasmic reticulum. The rough endoplasmic reticulum is particularly well developed in cells actively engaged in protein synthesis. Generally, it is found in that part of cytoplasm which is basophilic, a property which is attributed to attached ribosomes which contain RNA.
