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

To solve the question "Movement of sperm is due to," we will analyze the structure of sperm and the functions of its different parts.

### Step-by-Step Solution:

1. **Understanding Sperm Structure**:
- Sperm consists of three main parts: the head, the middle piece, and the tail.
- The head contains the acrosome and genetic material (DNA).
- The middle piece is rich in mitochondria, which provide energy.
- The tail is responsible for movement.

**Hint**: Remember the three parts of the sperm and their functions.

2. **Analyzing the Options**:
- **Option 1: Sperm Tail**: The tail is crucial for the movement of sperm. It moves in a whip-like fashion, allowing the sperm to swim towards the egg. This is the primary structure responsible for sperm motility.

**Hint**: Think about how a flagellum works in other cells and relate it to the sperm tail.

- **Option 2: Sperm Head**: The head contains the genetic material and is not involved in movement. Its role is to deliver DNA to the egg during fertilization.

**Hint**: Focus on the role of the head in genetic transfer rather than movement.

- **Option 3: Acrosome of the Sperm**: The acrosome is located in the head and is involved in the acrosomal reaction, which helps the sperm penetrate the egg's protective layer. It does not contribute to movement.

**Hint**: Consider the acrosome's function in fertilization rather than motility.

- **Option 4: Middle Piece of the Sperm**: The middle piece contains mitochondria that produce ATP, providing energy for movement. However, it is not directly responsible for the movement itself.

**Hint**: Recognize that while energy is crucial, it does not equate to the mechanism of movement.

3. **Conclusion**:
- After analyzing all options, we conclude that the movement of sperm is primarily due to the **sperm tail**. The tail's whip-like motion enables the sperm to swim toward the egg, making it the correct answer.

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