Head of sperm contains –

Options

A. Nucleus and mitochondria
B. Mitochondria and acrosome
C. Acrosome and nucleus
D. Nucleus, centriole and mitochondria

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of Sperm:**
- The sperm consists of three main parts: the head, the body (or midpiece), and the tail (or flagellum).

2. **Identifying the Components of the Head:**
- The head of the sperm is primarily composed of two key structures: the acrosome and the nucleus.

3. **Role of the Acrosome:**
- The acrosome is a cap-like structure that contains enzymes, such as hyaluronidase. These enzymes are crucial for the sperm to penetrate the outer layers of the egg during fertilization.

4. **Role of the Nucleus:**
- The nucleus within the head of the sperm carries the genetic material (DNA) from the male parent. This genetic material is essential for fertilization and the development of the embryo.

5. **Conclusion:**
- Therefore, the head of the sperm contains the acrosome (with enzymes) and the nucleus (with genetic material).

**Final Answer:**
The head of the sperm contains the acrosome and nucleus.
