4. Cyanobacteria and heterotrophic bacteria have been clubbed together in Eubacteria of kingdom Monera as per the "Five Kingdom Classification" even though the two areVasth different from each other. Is this grouping of the two types of taxa in the samekingdom justified? If so, why? |

Answer» Yes, although vastly different from each other, the grouping of cyanobacteria and heterotrophic bacteria in EUBACTERIA in Kingdom Monera is justified because both of them have certain common characteristics like: Both are unicellular Both are prokaryotes and lack a well-defined nucleus. The primitive nucleus is DEVOID of a proper nucleolus or nuclear membrane The genetic material or the DNA is scattered in the CYTOPLASM Both of them reproduce asexually. They both are highly contrasting in their methods of nutrition like cyanobacteria are AUTOTROPHS that prepare their own food; whereas, heterotrophic bacteria depends on some biomass for its food. SIMILARLY, cyanobacteria are mostly aquatic whereas heterobacteria depends on a host. |
