Which enzyme-containing, cap-like structure is present at the anterior end of the sperm head?
Answer and explanation
Correct answer: Acrosome
The acrosome is a cap-like vesicle at the anterior end of the sperm head. It contains enzymes, including hydrolytic enzymes, that help the sperm penetrate the coverings of the secondary oocyte during fertilisation. The nucleus stores paternal genetic material, mitochondria occur mainly in the middle piece, and the flagellum provides movement; therefore, option A is correct.
