Which part of sperm is formed by Golgi bodies ?

Options

A. Middle piece
B. Axial filament
C. Neck
D. Acrosome

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which part of the sperm is formed by Golgi bodies. The options provided are middle piece, axial filament, neck, or acrosome.

2. **Identifying the Role of Golgi Bodies**: Golgi bodies are essential cell organelles involved in the secretion and packaging of proteins. They play a crucial role in protein trafficking and sorting.

3. **Structure of Sperm**: A typical sperm consists of several parts:
- **Head**: Contains the nucleus and the acrosome.
- **Neck**: A slight depression below the head.
- **Middle Piece**: Contains spirally arranged mitochondria.
- **Tail**: The long flagellum that aids in movement.

4. **Focus on the Acrosome**: The acrosome is a cap-like structure located at the anterior part of the sperm head. It contains enzymes (sperm lysins) that are crucial for fertilization as they help in digesting the membrane of the ovum.

5. **Formation of the Acrosome**: During the development of sperm, specifically during the process called spermiogenesis, the Golgi bodies of spermatids give rise to the acrosome. This is because the Golgi bodies package the proteins (enzymes) produced by the endoplasmic reticulum into vesicles that form the acrosome.

6. **Conclusion**: Based on the information, the part of the sperm formed by Golgi bodies is the acrosome.

**Final Answer**: The part of sperm formed by Golgi bodies is **D) Acrosome**.
