Photosynthesis in Bacteria
Bacteria are a diverse group of organisms that can perform photosynthesis. However, the process of photosynthesis in bacteria differs from that of plants and algae.
Cyclic and Non-Cyclic Phosphorylation
Bacteria utilize both cyclic and non-cyclic phosphorylation during photosynthesis. Cyclic phosphorylation involves the transfer of electrons from a pigment molecule to a reaction center and back to the pigment molecule, resulting in the production of ATP. Non-cyclic phosphorylation involves the transfer of electrons from a donor molecule to a reaction center and then to an acceptor molecule, resulting in the production of both ATP and NADPH.
Light Absorption
Bacteria can absorb light of various wavelengths, but they do not absorb light greater than 800nm of wavelength. Bacteria have different types of pigments, such as chlorophyll, bacteriochlorophyll, and carotenoids, which enable them to absorb light of different wavelengths.
Oxygen Production
Unlike plants and algae, bacteria do not release oxygen during photosynthesis. Instead, they use different electron donors, such as hydrogen sulfide or organic compounds, to generate energy.
Use of Water
Most bacteria do not use water during photosynthesis. However, some photosynthetic bacteria, such as cyanobacteria, use water as an electron donor and release oxygen as a byproduct. The process of photosynthesis in these bacteria is similar to that of plants and algae.
In summary, bacteria can perform photosynthesis using different mechanisms and pigments. They do not release oxygen during photosynthesis, and most bacteria do not use water as an electron donor.

I think answer is 2 noncyclic phosphorylation is absent in bacteria & here we should not consider cyanobacteria
