  5. I, II, and III
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation
  • Domain is the broadest taxonomic category and includes one or more kingdoms.
  • Three domains of life are namely Bacteria, Archaea and Eukarya. Domain bacteria include kingdom bacteria, domain Archaea corresponds to kingdom Archaea and domain Eukarya includes kingdoms Protista, Plantae, Fungi, and Animalia.
    So, the correct answer is 'I, II, and III'
Multiple choice biology biodiversity and classification monera five kingdoms of living organisms biodiversity and need of classification

A unicellular prokaryote belongs to

  1. Animalia

  2. Eubacteria

  3. Fungi

  4. Plantae

  5. Protista
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Eubacteria, or "genuine" microbes, are single-celled prokaryotic microorganisms that have a scope of qualities and are found in different conditions all through all parts of the world. A wide range of microscopic organisms falls under this title, with the exception of archaebacteria. Since eubacteria are so normal, it contains one of the three areas of life; the three spaces are Archaea, Bacteria, and Eukarya.

Hence the correct option is B.

B Correct answer
Explanation

Among the given options, Animalia, Fungi and Plantae clearly fall under the eukaryotic domain. Protista can be considered as a heterogeneous group of eukaryotes as they consist of a nucleus enveloped in a nuclear membrane. Eubacteria basically refers to the entire bacterial population which will consist of unicellular prokaryotes.
