Answer 2

⚡HEY! MATE HERE IS YOUR ANSWER⚡

A) Cynobateria

Cyanobacteria are a group of photosynthetic bacteria, some of which are nitrogen- fixation, that live in a wide variety of moist soils and water either freely or in a symbiotic relationship with plants or lichen-forming fungi (as in the lichen genus Peltigera).


 They range from unicellular to filamentous and include colonial species. Colonies may form filaments, sheets, or even hollow spheres. Some filamentous species can differentiate into several different celltypes:
 vegetative cells – the normal, photosynthetic cells that are formed under favorable growing conditions;akinetes – climate-resistant spores that may form when environmental conditions become harsh; and thick-walled heterocysts – which contain the enzyme nitrogenase, vital for nitrogen fixation in an anaerobic environment due to its sensitivity to oxygen.
