Golgi complex is composed of

Options

A. Cisternae, tubules and vacuoles
B. Cisternae, tubules and vesicles
C. Cisternae, vesicles and vacuoles
D. None of the above

Answer

### Step-by-Step Solution:

1. **Understanding Golgi Complex**: The Golgi complex, also known as the Golgi apparatus or Golgi body, is a membrane-bound organelle found in eukaryotic cells. It plays a crucial role in the processing, sorting, and packaging of proteins and lipids that are synthesized in the endoplasmic reticulum (ER).

2. **Identifying Components**: The primary structural components of the Golgi complex include:
- **Cisternae**: These are flattened, disc-shaped membrane-bound sacs that make up the Golgi apparatus. They are essential for the processing and modification of proteins.
- **Tubules**: These are small, tubular structures that connect the cisternae and help in the transportation of materials within the Golgi complex.
- **Vesicles**: These are small membrane-bound sacs that transport proteins and lipids to their destination, either within the cell or outside of it.

3. **Evaluating Options**: The question provides several options regarding what the Golgi complex is composed of:
- **Option A**: Cisternae, tubules, and vacuoles
- **Option B**: Cisternae, tubules, and vesicles
- **Option C**: Cisternae, vesicles, and vacuoles
- **Option D**: None of the above

4. **Analyzing Each Option**:
- **Option A**: Incorrect because vacuoles are not a part of the Golgi complex; they are found in plant cells and lysosomes.
- **Option B**: Correct, as it includes cisternae, tubules, and vesicles, all of which are components of the Golgi complex.
- **Option C**: Incorrect because it includes vacuoles, which are not part of the Golgi complex.
- **Option D**: Incorrect because option B is a valid composition of the Golgi complex.

5. **Conclusion**: The correct answer is **Option B: Cisternae, tubules, and vesicles**.
