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.
