Which function of a sperm would be eliminated if a sperm lacked an acrosome?
Fully mature and leave the epididymis
Travel through the male reproductive ducts
Develop a full set of chromosomes
Breach end fertilize the ovum
The Correct Answer is D
A. Fully mature and leave the epididymis: The acrosome does not play a role in sperm maturation or their release from the epididymis.
B. Travel through the male reproductive ducts: Movement through the reproductive ducts relies on the sperm's flagellum and muscle contractions, not the acrosome.
C. Develop a full set of chromosomes: Chromosome development occurs during spermatogenesis and is unrelated to the acrosome.
D. Breach and fertilize the ovum: The acrosome contains enzymes that allow the sperm to penetrate the ovum during fertilization. Without an acrosome, the sperm would be unable to breach the egg’s outer layer.
