Explanation / Answer

Q no, 1

option D is incorrect and will be the answer

Explination

Protista are heterogeneous group of eukaryotic organisms, Specifically their nucleus is bordered by a nuclear envelope, and have organized plastids and mitochondria. Most protists are unicellular, but there are some relatively simple multicellular forms. This group is diverse and include organisms such as algae, slime molds and protozoa. They include both heterotrophic and autotrophic form. While as Kingdom Monera are single-celled organisms known as bacteria. microorganisms of this Kingdom (Monera) are considered as the most ancient living forms. Kingdom monera is divided into two groups Archaebacteria and Eubacteria. organisms included in this kingdom are prokaryotes. Their cells do not have nuclear membrane, lack membrane bound cellular organelles and their chromosome is a single and circular. Kingdom monera includes bacteria, cyanobacteria, mycoplasma etc. They do not have specific mode of nutrition and can be either aerobic or anaerobic.Their cell wall which is made up of peptidoglycans and Their cell organelles are not surrounded membrane. Cell organelles like mitochondria, endoplasmic reticulum, are absent.

D option is correct as all the microorganisms were included in kingdom monera

Explination

microorganisms being the primitive organisms.of the kingdom and are prokaryotes. these organisms are present in both living and non-living environment and can survive in harsh conditions like in hot springs, acidic soils etc.are single-celled organisms known as bacteria. microorganisms of this Kingdom are considered as the most ancient living forms. they are divided into two groups Archaebacteria and Eubacteria. organisms included in this kingdom are prokaryotes. Their cells do not have nuclear membrane, lack membrane bound cellular organelles and their chromosome is a single and circular. Kingdom monera includes bacteria, cyanobacteria, mycoplasma etc. They do not have specific mode of nutrition and can be either aerobic or anaerobic.

Answer

C option will be the answer

Explination

there is similaririty between archae and eukaryotes in the components of transcription and translation. archea bacteria is evolutionary considered as closest to eukaryotes as compeared will eu bacteria.
