The union of sperm and egg, known as fertilization, results in a zygote. This is the earliest stage of an embryo.

A fertilized egg cell is when a sperm enters an egg. The result is a fertilized egg cell, or a zygote.
Multiple sperm cells are involved in the process of fertilization, but only one sperm cell is needed to penetrate and fertilize the egg cell. Once the sperm cell penetrates the egg, it releases enzymes that break down the egg cell wall, allowing the genetic material of the sperm to enter the egg.
the egg is larger than the sperm cell

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.
A fertilized egg cell is when a sperm enters an egg. The result is a fertilized egg cell, or a zygote.
When a sperm cell penetrates an egg, and then implants itself in the lining of the uterus, a woman is considered pregnant.
Sperm and egg cells are the result of meiosis.
A fertilized egg cell is when a sperm enters an egg. The result is a fertilized egg cell, or a zygote.
In humans, the egg gets fertilized by the sperm in the fallopian tube. If the sperm successfully penetrates the egg, conception occurs.
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.

Through sexual intercourse. A man puts his penis inside a woman's vagina and thrusts it in and out until a fluid called semen comes out of his penis. The semen is filled with sperm. If one of the sperm cells finds the woman's egg cell, inside her vagina (one egg cell is released every month from the ovaries), and the sperm cell penetrates the egg cell and fertilizes it, then the cell starts developing into a baby.
The process when an egg cell and a sperm cell COMBINE is called Fertilization
A sperm and an egg.
the egg is larger than the sperm cell
It fuses with the membrane of the egg cell, and the content of the sperm cell enters the egg cell.
