What is regeneration?

Regeneration is when something fixes itself after getting hurt, just like a scraped knee heals.

Imagine you have a toy robot that can walk around. One day, it falls off the table and breaks into two pieces, its head and body are separated. But instead of staying broken forever, it slowly puts itself back together again, just like when your skin grows over a scrape. That’s regeneration!

Some robots can do this on their own, they have special parts that help them stick back together. In the real world, some animals can regenerate too! For example, if a starfish loses one of its arms, it can grow a whole new body from just that arm.

Not every robot has this power. Some might stay broken forever unless someone fixes them, just like how you need a bandage or some help to heal faster when you get scraped.

So regeneration is like having an inside repair shop that works automatically, helping things fix themselves without anyone needing to do anything!
