Why Do Fireflies Light Up and What Makes Fireflies Glow explained details in bengali
You must have watched fireflies lighting up your garden at night and wondered how they produce such brilliant, pulsating lights. Bioluminescence, a natural phenomenon that produces light in an organism, causes them to glow in such a manner. They flash every 5.5 seconds approximately.
Fireflies have an organic compound luciferin in their abdomen. It reacts with oxygen, calcium, and ATP (adenosine triphosphate) in the presence of the enzyme luciferase to produce light. This chemical reaction generates cold light, so it doesn’t heat up the light producing organ of the fireflies. It is because the whole chemical energy of the reaction is converted to light without losing any of it as heat, unlike light bulbs (where about 90% of the energy is wasted as heat). The required oxygen enters their body through the trachea, a complex network of fine tubes, as they don’t have lungs. When oxygen is available the fireflies glow, and extinguish when no oxygen can be spared.
