Question

Which feature, indicated in the following figure, do Chlorobi share with Chloroflexi and Chloracidobacterium thermophilum? 
A) chlorosomes 
B) thylakoids 
C) halophily 
D) endospores 
E) hormogonia

Quizplus · Accepted Answer

Chlorobi, Chloroflexi, and Chloracidobacterium thermophilum all have a specialized photosynthetic structure called chlorosomes, which allows them to efficiently harvest light in low-light conditions. Thylakoids are present in some, but not all, photosynthetic bacteria and are not unique to this group. Halophily refers to the ability to thrive in saline environments and is not a characteristic shared by these three bacterial groups. Endospores are a structure formed by some bacteria for survival in adverse conditions and are not present in Chlorobi, Chloroflexi, or Chloracidobacterium thermophilum. Hormogonia are specialized filaments that promote dispersal in some cyanobacteria and are not present in this group of bacteria.
