The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding RER**: The term RER stands for Rough Endoplasmic Reticulum. It is one of the two types of endoplasmic reticulum found in eukaryotic cells. 2. **Structure of Endoplasmic Reticulum**: The endoplasmic reticulum (ER) is a complex tubular network located in the cytoplasm of eukaryotic cells. It plays a crucial role in the synthesis and transport of proteins and lipids. 3. **Types of Endoplasmic Reticulum**: There are two types of endoplasmic reticulum: - **Rough Endoplasmic Reticulum (RER)**: This type has ribosomes attached to its cytoplasmic surface. - **Smooth Endoplasmic Reticulum (SER)**: This type lacks ribosomes on its surface. 4. **Reason for 'Rough' Appearance**: The presence of ribosomes on the Rough Endoplasmic Reticulum gives it a bumpy or rough appearance under a microscope. The ribosomes are the sites of protein synthesis. 5. **Conclusion**: Therefore, the Rough Endoplasmic Reticulum is termed 'rough' because it contains ribosomes, which are essential for protein synthesis. ---
