Have you ever looked in a mirror and noticed how it doesn't break, even though it's made out of glass? That's because there is something called a mirror support cell behind the mirror to keep it sturdy and strong.
A mirror support cell is like a bodyguard for a mirror. It's a special frame made out of strong materials, like metal or carbon fiber, that goes around the edges of the mirror. It's shaped kind of like a box, with flat sides and a hollow middle.
The mirror is mounted on the back of the support cell, so it's held securely in place. This way, even if you accidentally bump into the mirror, it won't fall out of the frame or break.
The support cell also helps the mirror stay flat and not bend or warp over time. This is really important, because if the mirror starts to bend or warp, then everything you see in the mirror will look weird and distorted.
So, the mirror support cell is like a superhero that protects your mirror from dangers and helps it stay strong and perfect.
