Bacteria use radiant energy between 870 to 1020 nm of the infrared region instead of visible light for photosynthesis. Thus the reaction center is B-890 which is the only pigment system present but both the cyclic and noncyclic reaction takes place in it. It utilizes hydrogen sulfide, thiosulphate as reducing power and does not evolve oxygen and maximum absorption is between 600 to 700 nm. Thus, the correct answer is option B.

Assertion. In bacteria photosynthesis occurs by utilising wavelength l...
Reasoning:
The assertion states that in bacteria, photosynthesis occurs by utilizing a wavelength longer than 700 nm. The reason provided is that the reaction center is B.
Explanation:
Photosynthesis in Bacteria:
- In bacteria, photosynthesis occurs through a process similar to that in plants, but with some variations.
- Bacteria like cyanobacteria and purple bacteria have specialized structures called chlorosomes that contain bacteriochlorophyll pigments for photosynthesis.
Utilization of Wavelength Longer than 700 nm:
- Bacteria that perform photosynthesis with bacteriochlorophyll utilize wavelengths longer than 700 nm for the process.
- This is because bacteriochlorophyll absorbs light in the infrared range, which has longer wavelengths compared to visible light.
Role of Reaction Center B:
- The reaction center in bacteria, particularly in purple bacteria, is denoted as reaction center B.
- Reaction center B is responsible for initiating the electron transport chain during photosynthesis in these bacteria.
Conclusion:
In conclusion, the reason provided for the assertion is correct. Bacteria utilize wavelengths longer than 700 nm for photosynthesis, and the reaction center B plays a crucial role in the process.
