What are the functions of the male and female germ cells?

The main task of the male gamete is to deliver chromosomes to the egg, while it has a tail, which provides movement, and an acrosome, whose enzymes will help to soften the protective layer of the egg. The ovum is immobile, larger in size, because it has reserves of yolk, which is needed to divide the zygote until it joins the tissues of the uterus and begins to receive nutrients from the body.
