NEETBotanyBiological Classification
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Archaebacteria are highly resistant and can survive in harsh habitats such as extreme salty areas and hot springs. Reason (R): Archaebacteria are able to survive in extreme conditions because they possess a cell wall structure similar to that of eubacteria. In the light of the above statements, cho
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A).
- BBoth (A) and (R) are true but (R) is not the correct explanation of (A).
- C(A) is true but (R) is false.
- D(A) is false but (R) is true.
Correct answer
C. (A) is true but (R) is false.
Step-by-step solution
Assertion (A) is true because Archaebacteria include halophiles (found in extreme salty areas) and thermoacidophiles (found in hot springs), which are known to survive in harsh habitats. Reason (R) is false because Archaebacteria differ from other bacteria (eubacteria) in having a different cell wall structure. This unique cell wall feature is exactly what is responsible for their survival in extreme conditions. Answer: (A) is true but (R) is false.
