Answer 2

Viruses were referred as "contagium vivum Fluidum" by D) Martinus Willem Beijerinck who was a Dutch biologist and a scientist researcher or is also known as "living infectious fluid".
Virus (termed as a literal meaning called poison) is a nucleoprotein entity which is able to utilize the biosynthetic machinery or a synthetic machinery of a living cell (or host) of another organism for its own benefit of multiplication which does not involve any sign of growth and division of the particle. Even before the discovery was being handed over there was a lot of extensive work on the virulente particles. Mosaic disease of Tobacco (originally given by Mayer et al 1886) was found to Ben the causative effect of a filterable agent present in the extract obtained from itself in the diseased tobacco mosaic plant by Ivanowski (in 1892). He is till now, has been credited with the discovery of the virus.
