Sperm cells. Coloured transmission electron micrograph (TEM) of a section through the testis,showing sperm cells. The heads of the sperm,which contain the genetic material,are blue. The central part of the cells,which contain the mitochondria that provide the energy for the cell,are brown. The ends of the tails are pink. The tail's motility is aided by the arrangement of microtubules (part of the cell cytoskeleton,dark brown and dark pink) within the tail. The microtubules are arranged in a central axoneme,with a central pair of microtubules surrounded by nine other pairs in a ring | |
