Sperm cell. Artwork showing the structure of a sperm cell,or spermatozoon,the male sex cell. It consists of a tapered head (red) that contains the genetic material,a basal body (top right) that contains mitochondria that provide energy for the cell,and a tail (centre and bottom) that beats to propel the sperm. A sperm's tail's ability to move is partly due to the arrangement of microtubules (part of the cell's cytoskeleton,green) within the tail. The microtubules are arranged in a central axoneme with two central single microtubules and nine peripheral double microtubules. Surrounding the microtubules are dense fibres (blue and orange),which provide rigidity and protection to the tail | |
