Sperm Diagram with Labels: A sperm diagram with labels illustrates the structure of a mature sperm cell, highlighting key components such as the head, midpiece, and tail (flagellum). The head contains the nucleus, which carries the fathers genetic material, and is capped by the acrosome, a specialized organelle containing enzymes that help the sperm penetrate the egg. The midpiece houses mitochondria that supply the energy required for motility. The tail propels the sperm forward using whip-like movements. This diagram is fundamental in understanding male reproductive biology and the journey of fertilization.
