what is the difference between embryo and zygote
Answers
Answer:
The terms embryo and fetus both refer to the developing baby inside the mother’s womb (uterus).
The distinction between embryo and fetus is made based on gestational age.
An embryo is the early stage of human development in which organs are critical body structures are formed.
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. The zygote divides to become a ball of cells that eventually implants in the wall of the uterus.
This ball of cells, known as a blastocyst, develops into the embryo and placenta.
Doctors date pregnancy from the first day of the last menstrual period.
