Question: 160: Given below are two statements: one is labelled as
Assertion (A) :
Spirulina is a microbe that can be used for reducing environmental pollution.
Reason (R) :
Spirulina is a rich source of protein, carbohydrates, fats, minerals and vitamins.
In the light of the above statements, choose the most appropriate answer from the options given below:
(1) Both (A) and (R) are correct and (R) is the correct explanation of (A)
(2) Both (A) and (R) are correct but (R) is not the correct explanation of (A)
(3) (A) is correct but (R) is not correct
(4) (A) is not correct but (R) is correct
Answer: Option (2)
Explanation:
Spirulina is a photosynthetic cyanobacterium that can be used in reducing environmental pollution because it can grow on wastewater and help in bioremediation by utilizing nutrients and reducing pollutants.
Thus, Assertion (A) is correct.
Spirulina is also a rich source of proteins, carbohydrates, fats, minerals, and vitamins, which makes it an important single-cell protein used as a nutritional supplement.
Hence, Reason (R) is also correct.
However, the nutritional richness of Spirulina does not explain its role in reducing environmental pollution.
Therefore, both (A) and (R) are correct, but (R) is not the correct explanation of (A).
