____________________ are special cells that are able to fix nitorgen and serve as fragmentation sites for certain types of bacteria.
A) filaments
B) cocci
C) akinetes
D) heterocysts
E) parenchyma

Question

Quizplus · Accepted Answer

Heterocysts are specialized cells found in some cyanobacteria that are capable of fixing nitrogen gas into ammonia, which then serves as a nutrient source for the organism. Heterocysts also serve as fragmentation sites for certain types of bacteria, which can help propagate the population. Filaments, cocci, akinetes, and parenchyma are all types of cells or cell structures, but they do not have the same specialized functions as heterocysts in terms of nitrogen fixation and fragmentation.
