What is a common example of bioluminescence?

• A. A glowstick
• B. A neon light
• C. A jellyfish
• D. A laser pointer

Answer: (C)

Bioluminescence is the phenomenon where living organisms produce and emit light through biochemical reactions. A common example of this is found in jellyfish, which contain a special protein called luciferin. This protein reacts with oxygen in the presence of an enzyme called luciferase, resulting in the emission of light. The bioluminescence in jellyfish can serve various purposes such as attracting prey or deterring predators. In contrast, the other options do not involve biological processes. A glowstick produces light through a chemical reaction that does not occur within a living organism; it is a man-made product. A neon light generates light using electricity to excite neon gas, while a laser pointer produces a concentrated beam of light through stimulated emission, none of which are biological processes. This understanding of bioluminescence emphasizes the unique ability of certain organisms to generate light, distinguishing them from artificial sources of illumination.
