A sperm is a cell consisting of a round or cylindrical nucleated cell, a short neck, and a thin motile tail.Its structure is vital to its mobility and function (i.e. sexual reproduction). The compacted nucleus contains half of the genetic information.t is produced by a male organism that unites with the egg of a female organism forming a zygote. Supplement.

On the other hand, a sperm cell is the smallest cell in the human anatomy. They have a small nucleus with a small volume of cell fluid, a long tail, and some mitochondria. They possess barely any content. They are the straightest type of cell. Egg and sperm cells are each otherâs contrast. The disparities are great.
