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.
Sperm cells are animal cells.
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.
A sperm cell will have 23 chromosomes, half the number found in a somatic cell. So, if there are 13 pairs of homologous chromosomes in the parental cell, there would be 26 chromosomes in the parental cell, but the sperm cell would have 23 individual chromosomes.
