When sperm and egg unite it is usually in the fallopian or uterine tube. It then can take up to 7 days for it to travel to the uterus for implantation.
The head of the sperm enters the oocyte. The flagellum remains outside.
the head
The sperm enters the egg (conception) in the fallopian tube.
At conception, the sperm enters the egg and the DNA of the sperm merges with the DNA of the Egg cell.
The sperm create an enzyme that eats away at the outer layer of the membrane of the egg allowing it to enter. The sperm then enters the egg and attaches its self.
It fuses with the membrane of the egg cell, and the content of the sperm cell enters the egg cell.
The process of uniting an egg with sperm is called fertilization.
Zygote
Once a sperm enters the egg, fertilisation of the egg begins.
The size of egg is larger than sperm because the the sperm enters inside the egg and egg has to accommodate the sperm. And egg contains fats and nutrients in order to feed zygote in case of pregnancy.
The sperm enters the egg cell.After nine months it will be a baby.But sometimes its just not successfull.
A fertilized egg cell is when a sperm enters an egg. The result is a fertilized egg cell, or a zygote.
Egg cells are the biggest: you could only fit one on the head of a pin. But I'm not sure if a sperm cell is bigger than a red blood cell or vice versa.
