Biology NEET on Instagram: "Heterocysts are specialized, thick-walled cells found in filamentous cyanobacteria like Anabaena and Nostoc, designed exclusively for nitrogen fixation. Unlike vegetative cells, heterocysts lack Photosystem II, so they do not produce oxygen, this is critical because the nitrogenase enzyme inside them is highly oxygen-sensitive. Nitrogenase, a metalloenzyme complex with Fe and Mo cofactors, converts inert atmospheric nitrogen (N₂) into ammonia (NH₃), a usable form for
