When an egg and a sperm comes together it is called sexual reproduction.
Fertilization is the process that results in the union of a male sperm cell and female egg cell.
Fertilization is the term for the union of the sperm and egg.

a zygote
Fertilization is the process describing the union of the sperm cell and the ovum.
Fertilization is the short answer. This process results in a fertilized egg known as a zygote.
assuming you mean a sperm and not a cingular cell of a sperm, it is about 1/18th the size of an ovum.
There's no such thing. The sperm cell comes from a boy. Ovum is another word for egg cell which is in a girl. When a sperm cell finds an "ovum" it fertilizes it and it travels to the uterus to develop eventually into a baby.
Ovum has a layer of zona pellucida around itself. When a sperm enters the ovum, the cortical granules present in the ovum, causes the thickening of the zona pellucida. This prevents the entry of other sperms in the ovum and only one sperm is able to fertilize the egg.
Their union forms the zygote.
A zygote is diploid, it is formed by the union of a male sex cell (a sperm) and a female sex cell (an ovum) both of which are haploid.
No, it is called an ovum.
Meiosis.
the sperm cells have to swim to the ovum and then fertilise it. and the egg cells have to reproduvce the offspring
The uniting of an egg and sperm cell is called unification
the egg will move into a position then the sperm cell will move closer]
