Assertion(A): Archaebacteria are special bacteria.Reason(R): They live...
Assertion (A): Archaebacteria are special bacteria.
Archaebacteria are indeed considered special due to their unique characteristics and evolutionary significance. They are distinct from regular bacteria (Eubacteria) and are classified under a separate domain of life.
Reason (R): They live in harsh habitats.
Archaebacteria are known for thriving in extreme environments such as hot springs, salt lakes, and deep-sea hydrothermal vents. Their ability to survive in these harsh conditions is a defining feature of this group.
Relationship between (A) and (R): Explanation
- Both are true:
- Assertion (A) is true as archaebacteria are indeed special due to their unique genetic and biochemical properties.
- Reason (R) is also true because their survival in extreme conditions is a hallmark of their uniqueness.
- Correct explanation:
- The fact that they live in harsh habitats is a significant reason why they are classified as special. Their adaptations to extreme environments, such as high temperatures, high salinity, and acidic conditions, highlight the evolutionary adaptations that set them apart from other bacteria.
Conclusion
Therefore, the correct answer is option 'A': Both (A) and (R) are true, and (R) is the correct explanation of (A). This relationship emphasizes the special nature of archaebacteria, rooted in their ability to thrive in some of the most inhospitable environments on Earth.
