When the female egg cell met with sperm
an organism
A fertilized egg cell is when a sperm enters an egg. The result is a fertilized egg cell, or a zygote.
Fertilization is a type of sexual reproduction wherein two different organisms produce a new organism. It is basically the union of a sperm cell and an egg cell.
Identical (monozygotic) twins develop from one zygote (fertilized egg) that splits into two embryos.

sex
A fertilized cell is when a mature ovum (egg) is fertilized by a sperm. It becomes a fertilized cell. The sperm enters the ovum and the tail drops off. Then mitosis occurs and the cell continues to develop.
A single cell that will develop into a chicken or rooster
The male produces sperm cells, which carry his genes. The sperm cell meets an egg cell from the female which carries her genes. The sperm cell penetrates the egg's outer layer. This is called "fertilizing" the egg. Normally, the outer layer of the fertilized cell thickens, so no more sperm cells can enter it. The fertilized egg then travels to the woman's uterus, where it attaches to the wall of the uterus and ultimately develops into a fetus.
In order to form a zygote (a fertilized egg) that ultimately matures into a baby, there has to be a union of the male and female gametes. The male gamete (or sex cell) is called sperm and the female gamete is called the ovum. When the sperm comes into contact with the ovum (or egg cell), it penetrates the egg cell and the process is caller fertilization. The fertilized egg transforms into a zygote and ultimately matures into a fetus, which then grows up into a child
