Golgi apparatus is made of

Options

A. Cisternae
B. Tubules and vesicles
C. Golgian vacuoles
D. All the above

Answer

### Step-by-Step Solution:

1. **Understanding the Golgi Apparatus**: The Golgi apparatus is a crucial organelle found in eukaryotic cells. It plays a significant role in modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.

2. **Components of the Golgi Apparatus**:
- **Cisternae**: The Golgi apparatus is primarily made up of flattened membrane-bound sacs known as cisternae. These structures are stacked on top of one another.
- **Tubules**: The Golgi apparatus also contains tubules, which are small tube-like structures that connect the cisternae and facilitate the transport of materials.
- **Vesicles**: Vesicles are small membrane-bound sacs that transport proteins and other molecules to and from the Golgi apparatus. They can contain various substances, including enzymes.

3. **Functionality of the Golgi Apparatus**: The Golgi apparatus has two main faces:
- **Cis Face**: This side receives vesicles from the endoplasmic reticulum (ER) containing newly synthesized proteins and lipids.
- **Trans Face**: This side is involved in sending out the processed proteins and lipids to their final destinations within or outside the cell.

4. **Conclusion**: Given that the Golgi apparatus is composed of cisternae, tubules, and vesicles, and considering the options provided:
- A. Cisternae
- B. Tubules and vesicles
- C. Golgi and vacuoles
- D. All of the above

The best answer is **D. All of the above**, as it encompasses all the components mentioned.

### Final Answer: D. All of the above
