Does the egg membrane strengthen shell?

The egg membrane does not directly strengthen the shell. However, it does play an important role in the overall structural integrity of the egg.

Here's how:

* Supporting the Shell: The egg membrane sits directly beneath the shell and provides some structural support. It helps to keep the shell from becoming too brittle and fragile.

* Preventing Cracked Eggs: The membrane also helps to prevent cracks from spreading. If a small crack does occur in the shell, the membrane can help to hold it together and prevent the egg from breaking completely.

* Gas Exchange: The egg membrane is involved in gas exchange between the developing chick and the outside world. It allows oxygen to enter the egg and carbon dioxide to escape.

In short, while the egg membrane doesn't make the shell itself stronger, it works alongside the shell to provide a protective barrier for the developing chick.
