The albumen (egg white) consists of about 10% protein dissolved in water. The albumens primary purpose is to protect the egg yolk and provide additional nutrition for the growth of the embryo, as it is rich in proteins, though it contains almost no fat. It also helps lubricate the growing embryo to allow for movement within the shell just prior to hatch.
my guess: placenta.
The one that has shockproof in it for PLATO users
It provides aqueous medium and protection .
The primary natural purpose of egg white is to protect the yolk and provide additional nutrition for the growth of the embryo (when fertilized).
A fertilized egg's yolk provides all of that embryo's nutrient, it also provides protection to the embryo. There are two types of yolk, white yolk and yellow yolk, both having their purpose.
The egg yolk is the part of the egg which feeds the developing embryo. The egg white protects the egg yolk and and provides additional nutrition for the growth of the embryo.
The white around the yolk., The yolk is the embryo.
Egg white holds the position of the embryo in the core (middle) of an egg shell.
In the egg, this is called the albumin.
When you peel a hard boiled egg you will first notice that after the shell is a white shell membrane, that is there to make sure the egg does not leak out of the pores. Next you will see the egg whites, this is albumen, a protein and water mix that is there to cushion the egg yolk and IF this were a fertilized egg, would provide water to the growing embryo.
The embryo is the yolk and feeds what would be the white of the egg if cooked.
The egg yolk is the main source of food for a developing embryo, and the albumin (egg white) supplies other nutrients as well as water to prevent the embryo from drying out.
Were an egg to become fertilized, this portion (the embryo) would become the actual chick, while the yoke provides nutrients to the embryo.
