Which is an organelle that helps the sperm to penetrate the ovum?
Correct answer: C. Acrosome
- A. Megalis
- B. Zona pellucida
- C. Acrosome
- D. Both A and B
Explanation
The organelle that plays a crucial role in helping the sperm penetrate the ovum (egg) during fertilization is the acrosome. The acrosome is a specialized structure located at the tip of the sperm cell's head. The acrosome is a vesicle filled with hydrolytic enzymes, particularly hyaluronidase, that are released when the sperm approaches the egg. These enzymes aid in breaking down the protective layers surrounding the egg, such as the zona pellucida. The penetration of the egg's protective layers allows the sperm to fuse with the egg's plasma membrane, initiating the process of fertilization.
