do you mean the egg?
A fertilized ovum, known as Zygote.
No.
yes
Blastocyst
Both are a hollow ball of cells
it is called a blastocyst
It splits into two cells and these split into two each and so on until you have a ball of cells. These are assigned various tasks. The phoetus implants into the uterus wall
When an embryo (fertilized egg) reaches the uterus, it is a hollow ball of about 100 cells called a blastocyst.
It takes about four days.
Blastocyst.
After two gametes fuse to form a fertilized egg, it starts to divide into more cells. In humans, this ball of cells becomes implanted in the wall of the uterus.
I am not sure but my biology teacher said it took 6-7 days
In the first developmental stage of the embryo, you have the ball of cells. In this ball of cells you have cavity filled with fluid called amniotic fluid. This fluid sac separates the embryo, from the outer non-embryo cells. Later on it encloses the fetus in amniotic fluid to give amniotic sac. This sac is attached to uterus from inside.
for successful fertilusation to take place the penis must enter the vagina and ejaculate spermazoa (sperm) into the vagina. the sperm then travels into the fillopian tubes where an egg will be making its way towards the uterus after ovulation. the sperm then fertilises the egg, this process forms a zygote. as the zygote travels towards the uterus clevage begins (clevage is the dividing of the ball of cells to form a ball of cells, reffered to as the embryo). the embryo then embedds into the uterine wall lining (endometrium) where it then begins its growth and development. the endometrium provides the embryo with nutrients for growth and development. after the emrbyo has had time to develope in around 9 months the baby will be born.
a baby develops in the uterus not in the mothers stomach a baby is a ball off cells at the begging and each Little cell will delope into skin hair nose eyes etc.
about the size of a tennis ball
No.
