Identify the part by each letter

**Structure of a Human Sperm Cell**

This diagram provides a detailed illustration of a human sperm cell and its interaction with an egg cell. The structure and components are labeled for educational purposes.

**A. Acrosome**: The acrosome is a cap-like structure that covers the anterior part of the sperm head. It contains enzymes necessary for penetrating the outer layers of the egg cell.

**B. Nucleus**: The nucleus is located within the head of the sperm cell and contains the genetic material (DNA) that will be combined with the genetic material of the egg during fertilization.

**C. Neck**: The neck is a short segment that connects the head of the sperm to the tail. It contains centrioles that play a role in cell division after fertilization.

**D. Tail (Flagellum)**: The tail, or flagellum, is a long, whip-like structure that propels the sperm forward, allowing it to swim through the female reproductive tract to reach the egg.

On the right side of the diagram, the sperm cell is shown approaching an egg cell. The anatomical parts of the egg cell are labeled as follows:

**E. Cytoplasm of Egg Cell**: The cytoplasm is the gel-like substance within the egg cell membrane, where cellular activities and processes occur.

**F. Zona Pellucida**: The zona pellucida is a thick, transparent layer that surrounds the egg cell. It plays a crucial role in sperm binding and prevention of polyspermy (fertilization by more than one sperm).

This diagram helps in understanding the intricate structure of human sperm cells and their role in the fertilization process with the egg. Understanding these components is fundamental in the study of human reproduction and embryology.
