The acrosome contains digestive enzymes essential for fertilization.

Explanation:
During fertilization, a sperm must penetrate the protective layers surrounding the egg. The acrosome is a cap-like structure at the tip of the sperm that holds digestive enzymes (such as acrosin) that break down the zona pellucida. This enzymatic action creates a passage for the sperm to reach and fuse with the egg’s plasma membrane, allowing fertilization to proceed. The nucleus carries the paternal chromosomes, not enzymes for penetration. Mitochondria generate energy for motility, and the flagellum propels the sperm but does not digest the egg's layers. Therefore, the acrosome's enzymatic contents are essential for fertilization.
