🌱 The Ultimate Solar-Powered Factory
Imagine a factory that runs entirely on sunlight, uses carbon dioxide as raw material, and produces both food and oxygen as output. Every green leaf on Earth is exactly that factory. Photosynthesis is the process that feeds virtually every living thing on the planet — and it all happens inside tiny organelles smaller than a grain of sand.
