Cisterne is found in -

Options

A. Only mitochondria
B. Only Endoplasmic Reticulum
C. Endoplasmic Reticulum and Golgi body
D. Only Golgi body

Answer

**Step-by-Step Solution:**

1. **Understanding Cisternae:**
- Cisternae are flattened, membrane-bound structures that resemble tube-like formations. They are essential components of certain organelles within the cell.

2. **Identifying Locations of Cisternae:**
- Cisternae are primarily found in two key cellular structures: the Endoplasmic Reticulum (ER) and the Golgi Apparatus (Golgi Body).

3. **Function of Cisternae:**
- In the Endoplasmic Reticulum, cisternae play a crucial role in the synthesis and transport of proteins to vesicles that then carry these proteins to the Golgi apparatus.
- In the Golgi apparatus, cisternae are involved in processing and modifying proteins and lipids, and they exist in different phases, namely cis, medial, and trans cisternae.

4. **Evaluating the Options:**
- Given the options:
1. Only in the mitochondria
2. Only in the endoplasmic reticulum
3. In the endoplasmic reticulum and Golgi body
4. Only in the Golgi body
- Based on the understanding that cisternae are present in both the Endoplasmic Reticulum and the Golgi apparatus, the correct answer is option 3.

5. **Conclusion:**
- Therefore, the correct answer to the question "Cisternae is found in -" is option 3: In the endoplasmic reticulum and Golgi body.
