explain what happen happen when egg fuses with sperm cell ?
Answers
When the sperm cell get in contact with a egg cell the egg cell membrane let's sperm come in by sperm releasing a enzyme to break to the membrane .
When the sperm nucleus gets suck so the egg cell nucleus fuses with sperm cell an start the process of making an baby .
fertilization occurs when the nucleus of both a sperm and an egg fuse to form a diploid cell, known as zygote. The successful fusion of gametes forms a new organism.Each month inside ovaries, a group of eggs starts to grow in small, fluid-filled sacs called follicles. Eventually, one of the eggs erupts from the follicle (ovulation). It usually happens about 2 weeks before next period.The corpus luteum releases a hormone that helps thicken the lining of uterus, getting it ready for the egg.At the instant of fertilization, baby's genes and sex are set. If the sperm has a Y chromosome, your baby will be a boy. If it has an X chromosome, the baby will be a girl. It keeps dividing as it moves slowly through the fallopian tube to the uterus. Its next job is to attach to the lining of uterus. This is called implantation.Most eggs are fertilized by sperm while still in the fallopian tube. The fertilized egg then travels down the fallopian tube into the uterus. This can take 1-2 days. When the egg reaches the uterus, it may attach itself to the uterine lining (the endometrium) and pregnancy will begin.
