What is the function of the acrosome in sperm?

  1. Encloses the marrow cavity

  2. Contains thermoreceptors for sweating

  3. Breaks down the outer membrane of the egg during fertilization

  4. Carries out lipid synthesis

The correct answer is: Breaks down the outer membrane of the egg during fertilization

The function of the acrosome in sperm is to break down the outer membrane of the egg during fertilization. This process is essential for the sperm to penetrate the protective barrier of the egg and successfully fertilize it. The acrosome contains enzymes that aid in degrading the outer layer of the egg, facilitating the sperm's entry into the egg for the fertilization process.
