Identify the incorrect match:
Show Hint
"Rhodo" = Photo/Light related.
Updated On: Jun 6, 2026
- Spherical shaped bacteria-Cocci
- Rod shaped bacteria-Bacilli
- Photoautotrophic bacteria-Chromatium
- Chemoautotrophic bacteria-Rhodospirillum
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Bacterial classification.
Step 2: Meaning
Classifying bacteria by morphology and metabolic mode.
Step 3: Analysis
*Rhodospirillum* is actually a photoautotrophic (specifically photoheterotrophic/photoautotrophic depending on classification) bacterium, not a chemoautotroph. All other matches are correct morphological or metabolic categorizations.
Step 4: Conclusion
*Rhodospirillum* is incorrectly matched as a chemoautotroph.
Final Answer: (D)
