Why are most plants and leaves green?
Look out a window and the world has a favorite color. Forests, lawns, weeds shoving through sidewalk cracks — green, green, green. It almost feels like plants got together and voted. But the real reason hides inside every leaf, and it starts with a tiny machine that eats light.
Plants make their own food. They don't hunt or shop; they cook sunlight into sugar. Inside each leaf are millions of little kitchens, and the head chef of every kitchen is a molecule called chlorophyll. Its job is simple: catch light, and use the energy to build food.
