Answer: Contains enzymes that digest the egg cell coating, allowing sperm to penetrate.
- A Provides chemical energy for sperm motility via mitochondrial respiration
- B Contains enzymes that digest the egg cell coating, allowing sperm to penetrate
- C Carries the haploid genetic material packaged tightly within the nucleus
- D Produces and powers the flagellum during late spermatid maturation
Correct answer: B. Contains enzymes that digest the egg cell coating, allowing sperm to penetrate
Explanation: The acrosome is a cap-like structure on the sperm head. It contains hydrolytic enzymes (hyaluronidase, acrosin) that digest the zona pellucida (egg coat), allowing the sperm to penetrate and fertilize the egg.
