After about a week from conception the zygote consists of over 100 cells. It then separates into two distinct mases. The outer cells form a shell that will become the placenta and the inner cells will become the embryo. First the outer cells must implant or embed themselves in the wall of the uterus. This occurs at about 10 days after conception.
If implantation occurs the cells will grow and become an embryo and placenta. An umbilical cord forms and connects to the embryo's stomach and placenta so the embryo can get nourishment.
An embryo gets nourishment inside the mother's womb through the placenta, which is an organ that develops during pregnancy. The placenta allows nutrients and oxygen to pass from the mother's bloodstream to the embryo and removes waste products from the embryo's blood. This ensures the embryo receives the necessary nourishment for growth and development.
Placenta
the developing embryo is nourished by yolk
to provide nourishment to the developing embryo in a seed
The embryo receives nourishment from the mother through the placenta, which allows for the exchange of nutrients, oxygen, and waste products between the mother and the developing fetus. This nourishment is essential for the growth and development of the embryo throughout pregnancy.
The embryo develops inside the uterus and receives nourishment through the placenta, which is formed from the tissues of both the mother and the embryo. The placenta allows for the exchange of nutrients, oxygen, and waste products between the mother and the developing embryo.
After the first few days of implantation, the embryo receives nourishment from the mother through the placenta. The placenta develops from tissues of both the embryo and the mother and allows for the exchange of nutrients, oxygen, and waste products between the mother and the embryo.
