Question

Assertion (A): Rhodospirillum is not a photoheterotroph bacteria. 
Reason (R): Photoheterotrophs obtain energy from light but carbon from organic sources.

• A. A and R are correct. R is the correct explanation of A
• B. A and R are correct. R is not the correct explanation of A
• C. A is correct but R is incorrect
• D. A is incorrect but R is correct

Hint:

Knowing different types of bacterial metabolism, like photoheterotrophy, is crucial for understanding ecological roles and biotechnological applications.

Answer 1

The Correct Option is D

Rhodospirillum is classified as a photoheterotroph, making the assertion incorrect. The reason provided correctly defines photoheterotrophs, highlighting the typical method of energy and carbon acquisition in these organisms.
