Answer Details

The part labelled I in the human sperm diagram is the acrosome. The acrosome is a specialized structure that covers the head of the sperm. It contains digestive enzymes that are necessary for the sperm to penetrate the protective layers of the egg during fertilization. When the sperm reaches the egg, the acrosome releases these enzymes, which break down the outer membrane of the egg and allow the sperm to enter and fertilize it. Therefore, the acrosome is a critical structure in the process of fertilization and is responsible for facilitating the fusion of the sperm and egg.
