Nucleus and acrosome
Explanation:
Human sperm is the male gamete or sex cell formed by spermatogenesis. It is made of a head, neck, a middle piece and a tail. The sperm head consists of a haploid nucleus and anterior to nucleus, an acrosome. The nucleus contains DNA and nuclear protein and it transfers genetic features from the male to the next generation. The acrosome contains an important enzymes, hyaluronidase and acrosin. These enzymes help to enter head into an ovum.
