Question

Viruses belong to the kingdom
A) Protista
B) Monera
C) Animalia
D) None of the above

Answer 1

Hint: Virus identification goes back to February 12, 1982, and it is discovered despite limited technological intervention. This was done in St. Petersburg, Russia by Dmitri Ivanovsky. This discovery was made even before the invention of the Electron Microscope. Six years later, this discovery by Dmitri Ivanovsky was confirmed by a Dutch microbiologist, Martinus Beijerinck. Finally, until the middle of the 20th century with the help of an Electron Microscope, the virus was confirmed. This study was credited to Ivanovsky and named the study as Virology.

Complete answer: A non-cellular, infectious agent which is microscopic in structure and can live by depending on the host cell is termed as a virus. Because of this parasitic nature and joined highlights of both living life forms and non-living substances, it can't be grouped under a living creature or nonliving. Because of this parasitic nature and consolidated highlights of both living beings and non-living substances, it can't be arranged under a living creature or nonliving. Because of the absence of required cell material, the infection can't repeat all alone external the host cell. To endure, it enters the host body and appends to a particular cell, at that point infuses the hereditary material, imitates by utilizing host hereditary material, lastly, the host cell parts and delivers the new infections. In less difficult terms, an infection is a non-cell, irresistible element with hereditary material and protein which attacks and imitates by utilizing the microorganisms inside the creature, plants, and creatures. Five kingdom classification was given by R.H. Whittaker. Classification of viruses has always been difficult as they are said to be a threshold of life. Therefore, viruses did not find any position in the five-kingdom classification.
Thus, the answer is option D: None of the above.

Note: The structure of the virus varies according to the organism it is living in. An infection molecule is covered with a defensive protein coat called capsid as the infection contains DNA or RNA. The state of the capsid changes as per the kind of infection. The proteins present in the viral qualities inside the genome comprise a viral capsid. Some viruses are coated with both phospholipids and proteins, this envelope is made by using a part of the host's cell membrane.
