What is the shell?

• A. Porous outer covering made of calcium carbonate
• B. Inner lining of the shell
• C. White albumin
• D. Chalazae

Answer: (A)

The shell is the porous outer covering of an egg, made mainly of calcium carbonate. This hard outer layer protects the contents while its tiny pores allow air and moisture to pass, which helps maintain freshness and can influence how the egg behaves during cooking. Inside the shell are the shell membranes, not the shell itself. The white albumin refers to the egg white, and chalazae are the rope-like strands that help anchor the yolk. So the shell’s defining feature is the calcium carbonate outer layer that surrounds and protects the egg.
