Shell Outside Hard Protective Covering made of Calcium Carbonate Very porous- 7,000 pores in a chicken eggshell
Membranes Two Membranes: Outer & Inner Protect the Egg s Contents from: Bacteria Moisture Leaving the Egg too Quickly
Air Cell As the Egg Cools, the Contents of Egg Contract More than the Shell Forms at the Large End of Egg
White/Albumen Provides the liquid medium in which the embryo develops Contains a large amount of protein
Vitelline Membrane Transparent Casing that encloses the Yolk Separates the Yolk from the Albumen
Chalaza Cord Like Attached to the Yolk Sac Hold it in the center of the egg Made of Mucin Fibers Special Form of Protein
Germinal Disk Contains the Female s Genetic Material Found on the yolk Small White Spot
Yolk Source of Food for Embryo Contains all the Fat in the Egg
