A mammalian embryo gets oxygen and nutrients from it mother by means of the umbilical cord which extends the embryonic blood supply into the placenta embedded in the mothers womb. The blood supply in the placenta is close to that of the mother and oxygen and nutrients diffuse across from the mother to the baby.
With egg laying animals the nutrients are supply to the embryo as the yolk part of the egg and oxygen is supplied by diffusion through the permeable shell and shell membrane
Through the umbilical cord.
its gets it all through the umbilical cord
The exchange of oxygen and carbon dioxide gas occurs through the eggshell. The chorion lines the inside surface of the egg and is connected to the blood vessels of the embryo.
The mammal embryo receives its nutrients from the mother through the placenta. The placenta allows nutrients to travel from the mother's system to the embryo's, and for waste products to leave the embryo's system so they can be disposed of by the mothers.
The Placenta uses a the process of diffusion to diffuse the nutrients from the mothers blood into the babies. Then the umbilical cord carries the nutrients to the baby to the Placenta. Answer is Placenta
This may be wrong, but I believe that it comes with the embryo it's self and provides nutrients.
The embryo is connected to the umbilical cord to the mother. The baby feeds on what its mother eats. Absorbs the nutrients and oxygen it needs. Drugs and other harmful substances will affect the embryo's development and it could possibly cause low birth weight, early birth. Also it will cause the embryo now a fetus have problems receiving oxygen and nutrients from its mother.
From its parent plant.
