Sperm have a body with a long tail, a neck, and a head.
The entire sperm body is enclosed by the plasma membrane.
The head contains the acrosome apically, which contains enzymes that facilitate sperm entry into the ovum. Thereafter, an expanded nucleus ( haploid) follows.
Numerous mitochondria can be found in the central portion, which provides the sperm with the energy it needs to move.
The tail, a flagellum that extends from the cell body, is what gives sperms their robust motility.
Sperms can swim to the ovum with the help of their tails.
Sperm motility:
Sperm motility is the ability of sperm to move properly through the female reproductive system.
