Placenta.
Placenta is the organ that is made from both tissue of the embryo and the mother. It forms during pregnancy for nutrient and waste exchange between the mother and fetus.
No, the egg does not stick to the placenta in the womb. The placenta is a temporary organ that develops during pregnancy to provide nutrients and oxygen to the growing fetus through the umbilical cord. The egg implants into the uterine lining and is surrounded by membranes, while the placenta forms separately.
