Vedclass · Answer

(C) Heterocysts are specialized,thick-walled cells found in certain filamentous cyanobacteria like $Nostoc$ and $Anabaena$.Their primary function is nitrogen fixation.They contain the enzyme nitrogenase,which is sensitive to oxygen.Because heterocysts have a thick wall and lack Photosystem $II$ (which produces oxygen),they create an anaerobic environment suitable for the nitrogenase enzyme to function efficiently in converting atmospheric nitrogen into ammonia.
