Questions
Identify the scientist who demonstrated that the extract of the infected plants of tobacco could cause infection in healthy plants and called the fluid as Contagium vivum fluidum
detailed solution
Correct option is A
The name virus that means venom or poisonous fluid was given by Pastuer. Dimitri Ivanowsky recognised certain microbes as causal organism of the mosaic disease of tobacco. These were found to be smaller than bacteria because they passed through bacteria-proof filters. M.W. Beijerinck demonstrated that the extract of the infected plants of tobacco could cause infection in healthy plants and called the fluid as Contagium vivum fluidum (infectious living fluid). W.M. Stanley showed that viruses could be crystallised and crystals consist largely of proteins. They are inert outside their specific host cell.Talk to our academic expert!
