Sperms of mammals depend for movement on

Options

A. Only tail
B. Middle piece
C. Head only
D. Tail and middle piece

Answer

**Step-by-Step Solution:**

1. **Understanding Sperm Structure**:
- Sperm are male gametes that are haploid in nature. They consist of three main parts: the head, middle piece, and tail.

2. **Identifying the Components**:
- The head contains the nucleus and the acrosome. The acrosome has hydrolytic enzymes that help in fertilization.
- The middle piece is rich in mitochondria, which are responsible for producing energy.
- The tail is responsible for the movement of the sperm.

3. **Role of Each Part**:
- The tail is crucial for the actual movement of the sperm, allowing it to swim.
- The middle piece, with its mitochondria, provides the necessary energy for the sperm to move.

4. **Conclusion**:
- The movement of sperm in mammals is dependent on both the tail (for propulsion) and the middle piece (for energy supply).

5. **Final Answer**:
- Therefore, the correct answer is that sperm of mammals depend for movement on both the tail and the middle piece.
