Which is correct about human sperm

Options

A. Acrosome serves no particular function
B. Acrosome has a conical pointed structure used for piercing and penetrating the egg resulting in fertilization
C. The sperm lysins in the acrosome disolve the egg envolope facilitating fertilization
D. Acrosome serves as a sensory structure leading the pserm towards the ovum

Answer

### Step-by-Step Solution:

1. **Understanding the Structure of Human Sperm**:
- Human sperm consists of four main parts: the head, neck, middle piece, and tail.
- Each part has specific functions that are crucial for fertilization.

2. **Analyzing the Head of the Sperm**:
- The head contains the acrosome, which is a cap-like structure filled with enzymes.
- The acrosome contains lysosomal enzymes that are essential for breaking down the protective layers surrounding the ovum, specifically the zona pellucida.

3. **Examining the Neck Region**:
- The neck of the sperm contains two centrioles.
- These centrioles play a role in cell division during fertilization.

4. **Exploring the Middle Piece**:
- The middle piece is rich in mitochondria, which provide ATP (energy) necessary for the sperm's motility.
- This energy is crucial for the sperm to swim towards the ovum.

5. **Understanding the Tail**:
- The tail (flagellum) is responsible for the motility of the sperm.
- It enables the sperm to swim and reach the egg for fertilization.

6. **Evaluating Statements about Human Sperm**:
- The question asks which statement about human sperm is correct.
- One statement suggests that the acrosome does not serve any particular function, which is false since it plays a crucial role in fertilization.
- Another statement correctly identifies that the acrosome contains enzymes that help dissolve the zona pellucida, facilitating fertilization.

7. **Conclusion**:
- The correct statement regarding human sperm is that the acrosome serves a vital function in fertilization by containing enzymes that help penetrate the ovum.
