💡 What is Bioluminescence?

Bioluminescence is the production of light by living organisms, like fireflies. It’s a chemical reaction inside their bodies that creates a beautiful glow.


⚗️ The Chemical Reaction

Fireflies use a molecule called luciferin and an enzyme called luciferase. When luciferin reacts with oxygen, catalyzed by luciferase, it produces light with almost no heat — a “cold light.”


🐞 Why Do Fireflies Glow?

  • To attract mates
  • To warn predators they taste bad
  • To communicate with other fireflies

🔬 Scientific Importance

Studying bioluminescence helps scientists develop new tools in medicine and biology, like glowing markers for imaging cells.
