How Does Bacteria Actually Multiply?

Bacteria multiply by splitting themselves into two tiny copies, just like a cookie splits into two halves.

Imagine you have a drawing on a piece of paper, and you want to make another one exactly the same. You could trace it, or maybe you could fold the paper in half and press it so both sides are the same. That’s kind of what bacteria do, they split themselves into two identical copies.

When a bacterium is ready to multiply, it grows bigger, then splits right down the middle like a cookie being broken apart. Each half becomes a new bacterium. It's like having a party where you make one more friend who looks just like you, and now there are two of you instead of one!

This splitting happens again and again, so soon there are many bacteria all looking the same, just like a group of identical twins playing together. Bacteria multiply by splitting themselves into two tiny copies, just like a cookie splits into two halves.
