  1. Parts of an EGG

  2. Shell -made of calcium carbonate -7,000 pores -allows transfer of gases through shell

  3. Outer Membrane -protects egg from bacteria Shell

  4. Outer Membrane Inner Membrane -protects egg from bacteria -prevents moisture loss Shell

  5. Outer Membrane Inner Membrane Shell Air Cell -as egg contents contract, air cell forms -older the egg, bigger the air cell

  6. Outer Membrane Inner Membrane Shell Thin Albumen -also known as egg whites -contains protein for development Air Cell

  7. Outer Membrane Inner Membrane Shell Thin Albumen Thick Albumen -also known as egg whites -liquid medium for development Air Cell

  8. Outer Membrane Chalazae Inner Membrane Shell Thin Albumen Chalazae -twisted strands of special proteins -suspend the yolk in the center of the egg Thick Albumen Air Cell

  9. Outer Membrane chalazae Inner Membrane Shell Vitelline Membrane -protects the yolk Thin Albumen Thick Albumen Chalazae Air Cell

  10. Outer Membrane chalazae Inner Membrane Shell Yolk -contains all the fat -source of food for the embryo Vitelline Membrane Thin Albumen Chalazae Thick Albumen Air Cell

  11. Outer Membrane chalazae Inner Membrane Shell Yolk Germ Spot -where the genetic information is found Vitelline Membrane Thin Albumen Chalazae Thick Albumen Air Cell
