Answer to this
Dear student,
Please find below the answer:
I. X is a virus
Y is protozoa
Z is bacteria
II. Microorganisms are living organisms that cannot be seen by the naked eye. Viruses are non-living infectious agents. They become active only when they enter the living cell. So they are not grouped under microorganisms.
III. X causes tobacco mosaic virus disease and tomato spotted wilt virus disease in plants.
Z causes leaf blight of wheat, the early blight of potato in plants.
IV. The type of virus causing death in china in recent times is the Coronavirus (SARS-CoV-2).
V. Antibiotics are medicines that inhibit the growth of bacteria and kill them. Antibiotics act by blocking certain biochemical pathways which are essential for the survival of bacteria like cell wall formation, protein synthesis, etc. For example, Penicillin is an antibiotic. It blocks the formation of the cell wall in bacteria, which makes bacteria weak and ultimately results in the death of bacteria.
Hope this clears your doubt.
Regards.
