When the female egg cell met with sperm
A fertilized egg, or zygote, develops in the uterus of the female reproductive system. The zygote undergoes cell division and forms into a blastocyst before implanting into the uterine lining, where it continues to develop into an embryo and then a fetus.
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 twins develop when a single fertilized egg splits into two embryos. In a female, this occurs shortly after fertilization in the womb. These twins share the same genetic material and are always the same sex.

Women become pregnant when a sperm cell from a male fertilizes an egg cell from a female. This typically occurs during sexual intercourse when sperm is ejaculated into the female's reproductive tract, traveling to meet the egg, usually released during ovulation. Once fertilized, the egg implants itself in the uterus, where it can develop into a fetus over approximately nine months.

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.
I think in botanical terms it the ovum, in mammals the ovaries.
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
An unfertilized egg is called an ovum. It is a mature female reproductive cell that has not been fertilized by a sperm cell.
