Which statement accurately describes the role of the acrosome in fertilization?

1. Sperm remains viable for a duration of 2-3 days.
2. The acrosome, located as a pointed structure at the tip of the sperm's nucleus, disintegrates prior to fertilization, releasing enzymes that help the sperm penetrate the follicular cells surrounding the egg, enabling fertilization.
3. The process of sperm formation in the testes occurs in three main stages: multiplication, growth, and maturation. During these stages, germ cells transform into spermatogonia, then into spermatocytes, which develop into spermatids and finally into sperm cells.
4. The complete process of spermatogenesis, resulting in mature sperm, takes approximately 74 days.

Correct answer: The acrosome, located as a pointed structure at the tip of the sperm's nucleus, disintegrates prior to fertilization, releasing enzymes that help the sperm penetrate the follicular cells surrounding the egg, enabling fertilization.

Solution

Option (b) correctly describes the role of the acrosome in fertilization, where it releases hydrolytic enzymes to penetrate the follicle cells surrounding the ovum.
