Explanation:
Detailed explanation-1: -The acrosome is a unique membranous organelle located over the anterior part of the sperm nucleus that is highly conserved throughout evolution. This acidic vacuole contains a number of hydrolytic enzymes that, when secreted, help the sperm penetrate the egg’s coats.
Detailed explanation-2: -Upon reaching an egg, enzymes contained within the sperm acrosome are activated, enabling the sperm to traverse the thick coat surrounding the egg (the zona pellucida); this process is known as the acrosome reaction.
