(N/A) human sperm cell is a microscopic structure composed of a head,neck,a middle piece,and a tail.
$1$. Head: Contains an elongated haploid nucleus and is covered by a cap-like structure called the acrosome,which contains enzymes that help in fertilization of the ovum.
$2$. Neck: Contains two centrioles,the proximal centriole (which helps in the first cleavage of the zygote) and the distal centriole (which gives rise to the axial filament).
$3$. Middle Piece: Contains numerous mitochondria that produce energy for the movement of the tail,which facilitates sperm motility.
$4$. Tail: $A$ long,flagellar structure that provides motility to the sperm,allowing it to swim towards the ovum.
