Solution

The correct option is B

Cycas


The correct option is B.

Explanation for correct option:

  1. Nitrogen fixation is an essential biological process and initial stage of nitrogen cycle.
  2. In this process, nitrogen in atmosphere is converted into ammonia (another form of nitrogen) by certain bacterial species like the Rhizobium, Azotobacter, etc. and by other natural phenomenon.
  3. Certain bacteria or the prokaryotes are capable of converting atmospheric nitrogen to ammonia.
  4. This process is generally called biological nitrogen fixation.
  5. The enzyme nitrogenase then converts nitrogen to ammonia.
  6. Nitrogen-fixing bacteria may be free-living or the symbiotic.
  7. Some of free-living nitrogen fixers are Azotobacter, Beijernickia, Rhodospirillum, cyanobacteria, etc.
  8. Nitrogen fixing symbiont roots are present in Cycas.

Final answer: A prokaryotic autotrophic nitrogen fixing symbiont roots are found in Cycas.
