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.

What is the function of the chalaza of the egg?
The chalaza in an egg is a rope-like, white "thing" that you might find in a scrambled or fried egg. If you look carefully, you can see it in a raw egg. What is does is it stabilizes or suspends the yolk, so that in a fresh egg the yolk floats in the middle of the albumin (egg white). When candling an egg, one thing you look for is that the yolk of an older egg will be near the shell and definitely visible. In a freshly laid egg, the you see a "shadow" of the yolk, and as you twirl the egg, the chalaza keeps the yolk in the center and away from the shell.
What size is the cell in an ostrich egg?
It kind of looks like a cell, with the yolk as a nucleus, but eggs, including ostrich eggs, are just growth chambers for the tiny embryo within. The embryo, being a living thing, is comprised of cells, but not the yolk which feeds the embryo or the white which cushions and hydrates the embryo. As the embryo grows the cells divide so the embryo contains more and more cells. The embryo uses the supplies inside the egg to create new cells as it grows into a chick.
Is an egg yolk really the largest single cell?
yes edit: No, even though that is what social media would have you believe. In reality the egg yoke is simply food for a microscopic normal sized cell. The yoke itself does not live nor act like a cell at all. Also even if you were to assume that by a vauge definition it were a cell (the same definition that would interpret my bladder as a cell) then yes it would be an abnormaly large cell, but not the largest. There is a kind of plant growing in south america which can get multiple meters in length. So im sorry but it is not the largest single cell, but that would be cool
