The Cheerful Crowd
What is a cell and why is it called the building block of life?
Pick up your hand and look at it. It feels like one smooth thing, right? Plot twist: it's actually a crowd. You are made of trillions of tiny living rooms, each one too small to see, each one busy and alive. We call them cells. And every single one of you is built out of them.
So what is a cell, really? It's the smallest piece of you that still counts as alive. Not "sort of alive." Fully alive. It eats, it cleans up its messes, it grows, and when the time is right, it makes a copy of itself. A grain of sugar can't do that. A cell can.
