4 MAIN PARTS:

  • TAIL- Back of sperm, flagellum structure that propels the sperm 
  • MIDPIECE- Contains mitochondria that provide the sperm with ATP energy (functionality, motility, etc.)
  • ACROSOME- Makes up majority of the front of sperm, contains special lysosome-like digestive enzymes that will digest outer layers of the egg during fertilization
  • HEAD- The front of the sperm structure that contains the acrosome and haploid nucleus (DNA)
