TED-Ed: The brilliance of bioluminescence - Leslie Kenna

The video explores the concept of bioluminescence, a natural phenomenon where living organisms produce light. It highlights how various creatures like fireflies, railroad worms, and deep-sea shrimp use bioluminescence for survival. The video explains the chemical processes behind bioluminescence and how scientists have harnessed this knowledge for genetic engineering, such as making tobacco plants glow. It also discusses the potential applications of bioluminescence, like creating sustainable lighting solutions, and encourages viewers to think about innovative uses for this natural light source.

What is the primary purpose of bioluminescence in organisms like the firefly?

• To camouflage

• To generate heat

• To attract mates

• To find food

How does the railroad worm protect itself from predators?

• By changing its color

• By emitting a foul smell

• By lighting up in two colors

• By hiding underground

What role do bioluminescent bacteria play in the life of an anglerfish?

• They help the fish digest food

• They provide light for attracting prey

• They clean the fish's skin

• They help the fish breathe underwater

What are the two chemicals involved in the bioluminescent reaction of a firefly?

• Glucose and insulin

• Luciferin and luciferase

• Adrenaline and dopamine

• Chlorophyll and hemoglobin

Why are engineers interested in developing bioluminescent trees?

• To increase oxygen levels

• To provide natural lighting

• To reduce noise pollution

• To improve air quality
