Have you ever wondered what you are eating when you eat eggs? Well, today we found out exactly what everything is called inside an egg and what their functions consist of for a growing chick.
We broke open an egg and observed it with a magnifying glass. After cracking an egg, one can see something somewhat gooey inside the eggshell. This insulates the contents of the egg. The shell is the hard outer membrane. The yolk is similar to the placenta in humans. It provides nourishment to the developing chick. The white spiral bands on either side of the yolk are called chalazae. They hold the egg yolk in place. The part of the egg that is the egg white is called the albumen. It contains water reserves for the growing chick.
We labeled the parts of the egg as shown above.
shell = outer membrane = protection
inner gooey part of shell = inner membrane = insulation
yolk = food source for the developing chick
squizzly white bands = chalazae = holds yolk in place
egg white = albumen = water reserves for the chick
