The allantois and yolk are attached to the reptile embryo. The allantois performs two very important functions for the embryo, providing for gas diffusion, and removal of wastes. Color the allantois green. Food for the developing embryo comes from the yolk sac, which reduces in size as the embryo matures. Color the yolk sac yellow. Surrounding all the other membranes is the chorion, providing an overall enclosure for the young. Around the chorion is the albumin, or white of the egg.
