Q. Which one of the following statements about human sperm is correct?
(a) Acrosome serves no particular function.
(b) Acrosome has a conical pointed structure used for piercing and penetrating the egg resulting in fertilization.
(c) The sperm lysins in the acrosome dissolve the egg envelope facilitating fertilization.
(d) Acrosome serves as a sensory structure leading the sperm towards the ovum.
Solution :
Correct option : C Acrosomes contain digestive enzymes like hyaluronidase and lysins, which helps in breaking down the outer membrane of the ovum called as the zona pellucida, allowing the haploid nucleus in the sperm cell to join the haploid nucleus in the ovum, thus enabling fertilization. Hence, the correct answer is option C.
