With reference to Bioluminescence, consider the following statements: 1. It is mainly produced by microscopic plankton called dinoflagellates, though it is also widespread among deep-sea animals. 2. The light emission results from a reaction between the enzyme luciferase and the compound luciferin in the presence of oxygen. 3. The phenomenon is confined only to tropical oceans and cannot be observed in Indian waters. Which of the statements given above is/are correct? |ForumIAS

[A] 1 and 2 only

[B] 2 only

[C] 1 and 3 only

[D] 1, 2 and 3

Answer: A

Notes:

Explanation:

Dinoflagellates are primary sources, though many marine species (fish, jellyfish, worms, arthropods, etc.) also exhibit bioluminescence.
The light emission results from a reaction between the enzyme luciferase and the compound luciferin in the presence of oxygen.
Bioluminescence has been observed in India (e.g., Havelock, Thiruvanmiyur, Mattu, Bangaram).
