Question

A successful study of morphology of viruses can be done by

• A. Binocular microscope
• B. Plane polarised microscope
• C. Electron microscope
• D. Simple microscope

Answer 1

Answer: (C)

Electron microscope

A virus is an infectious agent of small size and simple composition that can multiply only in living cells of animals, plants or bacteria. Viruses are microscopic; they range in size from about 20 to 400 nanometers in diameter. An electron microscope is a microscope that uses accelerated electrons as a source of illumination. Because the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons, the electron microscope has a higher resolving power than a light microscope and can reveal the structure of smaller objects. So, an electron microscope is used to study the morphology of viruses. Thus, option C is correct.
Binocular microscope, plane polarised microscope and simple microscope resolution are not sufficient to study the morphology of viruses.
