Which describes the function of the human sperm cell’s structure?

Sperm, are known for having a somewhat pointed "head" or cell body, and "Flagella". These are very important parts, because the head is designed to be able to puncture the cell membrane of a unfertilized ovum. The Flagella is the waggling fin that the sperm cell uses to swim up the female reproductive tract to the ovum which should be in the Fallopian tubes.
