The correct Answer is:
### Step-by-Step Solution 1. **Identify R.E.R**: R.E.R stands for Rough Endoplasmic Reticulum. It is an organelle found in eukaryotic cells. 2. **Characteristics of R.E.R**: The Rough Endoplasmic Reticulum is characterized by the presence of ribosomes on its cytoplasmic surface, which gives it a "rough" appearance. 3. **Function of R.E.R**: The primary function of the Rough Endoplasmic Reticulum is to synthesize proteins. The ribosomes on its surface are the sites of protein synthesis. 4. **Structure of R.E.R**: The Rough Endoplasmic Reticulum is composed of flattened membranous sacs called cisternae, interconnected tubules, and vesicles. 5. **Additional Information**: In the context of the question, it is important to differentiate R.E.R from other types of endoplasmic reticulum (like Smooth Endoplasmic Reticulum), and also to clarify that the term "neutrophilic" mentioned in the video refers to a type of white blood cell, not directly related to R.E.R. 6. **Conclusion**: Therefore, R.E.R or Rough Endoplasmic Reticulum is an essential organelle in eukaryotic cells responsible for protein synthesis.
