Why Yolk is absent in human egg?
A bird's egg is a self-contained unit. Everything the fetus needs to grow to birth weight is contained in the egg. The yolk provides the nutrients to bring that single-cell egg to birth stage. In humans, the nutrients are provided from the mother to the fetus by the umbilical cord.
Why is the egg yolk cell so big?
The yolk is a source of energy for the embryo to live off of once the egg has been laid. The embryo is actually a part of the yolk membrane, a mere little white dot on the membrane of the much larger yolk sac. Since the embryo has no external source of energy to grow from, unlike mammals grown in the womb of their mothers do, the yolk sac acts as that source of energy for the embryo and chick fetus to grow from. Fetal mammals, in comparison, have a placenta and umbilical cord that anchors that fetus to the mother, allowing the mother to give nutrients to her fetus from the external food sources she eats. The yolk is high in saturated fatty acids, protein and carbohydrates which is everything a growing chick-fetus needs to grow in the egg. A few days before the chick is hatched, the yolk sac is enveloped by the chick into the chick's abdomen. This continue to provide a source of energy for a day or two after the chick has been hatched, but is absorbed into the chick's abdominal cavity once all the energy has been used up and the chick begins to eat on its own.
