Movement of sperm is due to

Options

A. Sperm tail
B. Sperm head
C. Acrosome of the sperm
D. Middle piece of the sperm

Answer

### Step-by-Step Solution:

1. **Understanding the Structure of Sperm**:
- Sperm is a male gamete that is essential for fertilization. It consists of three main parts: the head, middle piece, and tail.

2. **Identifying the Functions of Each Part**:
- **Sperm Head**: Contains the nucleus and the acrosome. The acrosome is important for penetrating the egg during fertilization but does not contribute to movement.
- **Middle Piece**: Contains mitochondria, which are responsible for producing energy (ATP) necessary for the sperm's movement. However, it does not directly cause movement.
- **Sperm Tail**: Composed of a central axial filament and is responsible for the motility of the sperm. It propels the sperm forward.

3. **Analyzing the Options**:
- **Sperm Tail**: Known for its role in the movement of sperm due to its whip-like motion.
- **Sperm Head**: Involved in fertilization, not movement.
- **Acrosome**: Aids in penetrating the egg, not in movement.
- **Middle Piece**: Provides energy but does not directly cause movement.

4. **Conclusion**:
- The movement of sperm is primarily due to the **sperm tail**, which is designed for motility.

### Final Answer:
The movement of sperm is due to the **sperm tail**.
