biology living world and classification of microbes modern classification system traditional method of animal classification salient features of five kingdoms classification hierarchy hierarchy of classification

  1. Bacteria

  2. Lichens

  3. Cyanobacteria

  4. Viruses

Show answer
Correct Option: D
Explanation:

Viruses are considered to be acellular as they do not have a defined cell wall, cell membrane, nucleus or nucleoid, cytoplasm and cellular organelles. For this reason, they cannot perform their metabolic activities on their own and are obligately dependent on the host cell machinery. Therefore, they do not find a place in the five-kingdom classification system. 

A. Bacteria are classified under Kingdom Monera as they have a prokaryotic cell.
B. Lichens are grouped under Kingdom Fungi.
C. Cyanobacteria are photosynthetic prokaryotes grouped under Kingdom Monera.
D. No kingdom is ascribed to the viruses.
Hence, the correct answer is 'Viruses'
