What are the functions of the different parts of an egg?

An egg consists of several key parts, each serving specific functions. The shell provides protection and a barrier against bacteria while allowing gas exchange. The egg white (albumen) primarily serves as a source of water and protein for the developing embryo. The yolk contains nutrients, fats, and vitamins, providing the energy needed for growth, while the chalazae help anchor the yolk in the center of the egg, maintaining its position.
