they have long tails for swimming and heads to get into the ovum
In animals it would be called a sperm. In plants I assume the answer would be the pollen, however, the pollen is not necessarily one cell. Even if it is one cell it will have more than one nucleus (2 or 3).
a sperm cell
You would find a sperm cell in the testes of the male reproductive system.
The human gametes are the sperm cell (male) and the egg cell (female). The chromosomes carried by the sperm cell can have two forms, the X cell (female offspring) or the Y cell (male offspring). These combine with the egg cell, which virtually always carries only an X chromosome. So an XX cell would develop as a female, and an XY cell would result in a male offspring.
No, sperm is not present in the nucleus. Sperm is a specialized reproductive cell that contains genetic information, including chromosomes, that is located in the nucleus of a male organism's reproductive cells. The nucleus of a cell contains the majority of the genetic material, while the sperm itself is produced in the testes.

The mutation must be present in the Reproductive cell, Ovum/Egg in females (present in the Ovary) and Sperm in males.
A large concentration of mitochondria are present in the tail section of the sperm. The mitochondria are the energy components, and the tail needs the energy for it's journey to fertilization.

Stupid, stupid person....what makes contact with the egg cell: the sperm cell or the muscle cell? Seriously, use your head.
a sperm cell
The acrosome, which contains enzymes that help the sperm penetrate the egg, and the flagellum, which allows the sperm to swim towards the egg, are two structures found in sperm cells that are not present in animal cells.
So that the sperm can break through to fertalise the egg.Because it enters to egg cell through its head only. The enzymes present at the top of its head facilitate the penetration of sperm in the egg cell.
