With reference to the Bioluminescence,considerthe following statements...
Bioluminescence is the production and emission of light by living organisms. It is a fascinating natural phenomenon that occurs in various organisms including bacteria, fungi, insects, fish, and marine planktons. In the context of this question, we will focus on bioluminescence in marine planktons called dinoflagellates.
**Statement 1: It occurs due to the presence of marine planktons called dinoflagellates.**
This statement is correct. Bioluminescence in the ocean is primarily caused by the presence of dinoflagellates, which are single-celled organisms found in marine environments. These organisms exhibit bioluminescence when they are disturbed, such as when waves or boats pass through the water. The bioluminescence is a result of a chemical reaction within the dinoflagellate cells, involving a luciferin molecule and an enzyme called luciferase. When the luciferin reacts with the luciferase and oxygen, it produces light.
**Statement 2: This phenomenon is possible only in the ocean waters.**
This statement is incorrect. While bioluminescence is commonly associated with the ocean and marine environments, it is not exclusive to them. Bioluminescence can also occur in other ecosystems such as freshwater, terrestrial, and even aerial environments. For example, fireflies are well-known terrestrial organisms that exhibit bioluminescence. There are also bioluminescent fungi and bacteria found in various habitats. However, it is true that bioluminescence is more prevalent and diverse in the ocean due to the abundance of marine organisms that possess this ability.
Therefore, the correct answer is option A) 1 Only. Bioluminescence occurs due to the presence of marine planktons called dinoflagellates, and it is not exclusive to the ocean waters.

Community Answer
With reference to the Bioluminescence,considerthe following statements...
Recently, a group of MTech students noticed something unusual along the coast of Visakhapatnam which was glowing due to a unique natural phenomenon called bioluminescence.
- What is it? Bioluminescence occurs due to the presence of some marine planktons called dinoflagellates that produce light when the water is disturbed.
- These planktons emit light on the ocean surface at night.
- Bioluminescent is widespread among deep sea animals in general.
- Many marine creatures like sponges, jellyfish, worms, species of fish, anthropods, echinoderms and unicellular alga exhibit bioluminescence to either evade predators, attract prey or during mating.
- In Visakhapanam, this phenomenon is most likely the result of an algal bloom of the dinoflagellate species of noctiluca and ceratium.
- This occurs when the luciferase enzyme reacts with luciferin compound in the presence of oxygen to produce a cold light.
- This is widespread in lagoons and sometimes breakwaters and is particularly visible during warm weather conditions.
- The dinoflagellates follow a circadian cycle (24-hour cycle) and as a result this phenomenon occurs during the night which is visible in low light conditions.
- This unique phenomenon has been visible in some other beaches in India including Havelock Island in the Andamans, Thiruvanmiyur beach in Chennai, Mattu beach in Karnataka and Bangaram Island in Lakshadweep.
Hence only statement 1 is correct.
