When the human egg is fertilized and becomes a zygote and then a developing embryo, it derives its food from the placenta.
The developing embryo is nourished by the yolk sack until implantation. Upon implantation the placenta begins to develop, the placenta acts as the fetal lung , it transports oxygen to the fetus and carbon dioxide away from the fetus via the umbilical cord. The placenta also provides stored carbs for the developing fetus.
Supply food to the developing embryo is the purpose of the cotyledon.

It's a sack and not an egg but the primary food source, the only one, is the placenta and the nutrients go via the umbilical cord.
