Verified step by step guidance1
Identify the main components of a sperm cell: acrosome, nucleus, midpiece, and flagellum.
Understand the function of each component: the acrosome contains enzymes to penetrate the egg, the nucleus holds genetic material, the midpiece contains mitochondria for energy, and the flagellum is responsible for movement.
Focus on the function related to movement: the flagellum is a whip-like structure that propels the sperm forward.
Recognize that the flagellum's movement is powered by ATP produced in the midpiece, but the actual propulsion is due to the flagellum's motion.
Conclude that the structure responsible for propelling a sperm forward in the female reproductive tract is the flagellum.
