What is the difference between zygote and fetus?



There is clearly huge difference between a zygote and foetus.

Where zygote is actually :

1)The product of fusion of the nuclei of the sperm and egg is called zygote.

2)It is a unicellular structure. i.e single cell containing diploid(43 chromosomes)in nucleus.

Whereas foetus is actually formed by multiple divisions of zygote.

1)The stage of the embryo which nearly resembles a human being is called a foetus.

2)It is a multicellular structure.

Answer 2

The terms embryo and fetus both refer to the developing baby inside the mother's womb (uterus). ... An embryo is termed a fetus beginning in the 11th week of pregnancy, which is the 9th week of development after fertilization of the egg. A zygote is a single-celled organism resulting from a fertilized egg.
