Question

Ceratium fusus is a protist that is found primarily in coastal waters, especially around the coast of the United Kingdom. These organisms are unique because they can undergo a special chemical reaction at night that helps defend them against predators. It provides defense by attracting larger predators that prey on the organisms that eat Ceratium fusus. Which characteristic of Ceratium fusus is being described? photosynthesis glass-like cell walls bioluminescence chitin cell walls.

Answer 1

A chemical defense mechanism is called bioluminescence.

As mentioned in the reaction, Ceratium fusus undergoes a special chemical reaction at night which helps them defend themselves from predators. During this reaction, light is produced inside a living organism. However, this type of reaction does not produce heat although it does produce light.

What is bioluminescence used for?

The most well-known purpose of bioluminescence is to defend the organism against attacks by predators. This is because the light confuses or frightens predators.

Besides confusing the predator, the light can also alert large predators to approach the location of the organism, in this way this large predator will eat the predator that is threatening the organism which in our question, is Ceratium fusus.

Many marine organisms use the phenomenon of bioluminescence for their defense, in particular marine invertebrates, vertebrates, certain micro-organisms as well as certain fish and fungi.

Hence concluded that the bioluminescence characteristic of Ceratium fusus is being described.
