In which part of sperm, mitochondria are present?

Options

A. Head
B. Tail
C. Neck
D. Middle piece

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of Sperm**: Sperm is composed of several parts: the head, neck, middle piece, and tail. Each part has a specific function.

2. **Identifying the Parts of Sperm**:
- **Head**: Contains the acrosome, which has enzymes to help penetrate the ovum, and genetic material.
- **Neck**: Connects the head to the middle piece.
- **Middle Piece**: This part is crucial as it contains mitochondria.
- **Tail**: Responsible for the movement of the sperm towards the ovum.

3. **Locating Mitochondria**: Mitochondria are present in the middle piece of the sperm. This is important because they are the powerhouses of the cell, providing the necessary energy for the sperm's movement.

4. **Function of Mitochondria**: The primary function of the mitochondria in the middle piece is to produce ATP (adenosine triphosphate), which is essential for the motility of the sperm. This energy allows the sperm to swim and reach the ovum for fertilization.

5. **Conclusion**: Therefore, the part of the sperm where mitochondria are present is the middle piece.

**Final Answer**: Mitochondria are present in the middle piece of the sperm.
