Chemical Reactions: Bioluminescence

Bioluminescence is a type of light produced through a chemical reaction. In jellyfish, when a predator makes contact, two chemicals react to form a new substance that emits light. This light startles the predator, allowing the jellyfish to escape.

What is the term used to describe the light produced by certain organisms?

• Fluorescence

• Incandescence

• Bioluminescence

• Photosynthesis

What triggers the chemical reaction that produces light in jellyfish?

• Presence of food

• Contact with a predator

• Water temperature

• Sunlight

How many different chemicals are involved in the jellyfish's light-producing reaction?

• One

• Four

• Two

• Three

What is the purpose of the light emitted by jellyfish?

• To navigate in the dark

• To find food

• To startle predators

• To attract mates

What advantage does bioluminescence provide to jellyfish?

• It gives them a chance to escape predators

• It allows them to blend in with their surroundings

• It helps them communicate with other jellyfish

• It helps them swim faster
