Acrosome of sperm is derived from

Options

A. Golgi vesicle
B. Lysosome
C. Golgi tubule
D. cisternae

Answer

### Step-by-Step Solution:

1. **Understanding the Acrosome**: The acrosome is a cap-like structure found on the head of sperm cells. It plays a crucial role in fertilization by containing enzymes that help the sperm penetrate the outer layers of the egg.

2. **Identifying the Source of the Acrosome**: The acrosome is formed during the development of sperm cells. It is specifically derived from the Golgi apparatus, which is an organelle involved in the processing and packaging of proteins and lipids.

3. **Role of the Golgi Apparatus**: The Golgi apparatus produces materials for secretion and is involved in the transformation of membrane-bound vesicles. It synthesizes glycoproteins and other substances that are essential for various cellular functions.

4. **Formation of the Acrosome**: During spermatogenesis, the Golgi apparatus forms vesicles that eventually fuse to create the acrosome. This process includes the accumulation of enzymes that are critical for the sperm's ability to fertilize an egg.

5. **Conclusion**: Therefore, the correct answer to the question "Acrosome of sperm is derived from" is the Golgi apparatus.

### Final Answer:
The acrosome of sperm is derived from the Golgi apparatus.
