Question

Give two differences between a zygote and foetus in the short term

Answer 1

zygote:1) it is the initial stage of the baby when the fertilisation takes place.
2) it is just a single cell.
foetus:1) it is formed by rapid division of cells of zygote.
2) it is formed in the later stages of development i.e some months after fertilisation.

Answer 2

Explanation:

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.
