In which of the following oxygen does not evolve during photosynthesis?
1 Photosynthetic red algae
2 Photosynthetic green algae
3 Photosynthetic blue-green algae
4 Photosynthetic bacteria
Explanation:
Photosynthetic bacteria does not evolve oxygen during photosynthesis. Photosynthetic bacteria directly utilize energy from solar radiation and electron from inorganic or organic compound. The photolysis of $\mathrm{H}_{2} \mathrm{O}$ does not takes place in photosynthetic bacteria so oxygen is not involved.

Of the following statements which are not relevant to Archaebacteria?
1 A, B and C
2 A, C and E
3 C, D and E
4 A, C and D
5 B, C and E
Explanation:
Archaebacteria live in some of the harsh habitats. They have cell wall which is made up of polysaccharides and protein, without peptidoglycan. They are also present in the gut of several ruminant animal.

The nature of photosynthesis in blue-green algae is
1 Oxygenic
2 Anoxygenic
3 Anaerobic
4 None of these.
Explanation:
The oxygenic photosynthesis performing organisms are called Cyanobacteria. The blue-green algae were the first oxygenic photoautotrophs on the planet earth. It is found in eukaryotes.

Which of the following is free living aerobic, non- photosynthetic nitrogen fixing bacterium?
1 Rhizobium
2 Azotobacter
3 Nostoc
4 Azospirillium
Explanation:
Azotobacter are free living aerobic and non photosynthetic nitrogen fixing bacteria. It retains the capability of fixing atmospheric nitrogen i.e. fixation of atmospheric nitrogen into ammonia.
