Solution

Sperm is the male gamete that fuses with female gamete and produce a diploid cell called zygote. During fertilization, acrosome of the sperm releases some enzymes, particularly hyaluronidase, that facilitates the penetration of the sperm into ovum. These enzymes dissolve the membrane enveloping the ovum and help the sperm head to enter the ovum.
