Final answer:
A hen's egg consists of the shell, egg white or albumen, yolk, and chalaza, with the yolk containing most of the egg's fat.
Step-by-step explanation:
There are four main parts to a hen's egg:
- The shell provides protection and is mostly made of calcium carbonate.
- The egg white, or albumen, contains water and proteins and serves to protect the yolk and provide additional nutrients.
- The yolk contains the majority of the egg's fat and is rich in proteins, fat-soluble vitamins, and essential fatty acids.
- The chalaza, which are cord-like structures that hold the yolk in the center of the egg white.
The majority of the fat in an egg is located in the yolk.
