Virus are microparticles which consists of genetic material and protein coat some time an enevelop is also seen on them. Their size is measured in nanometer. Their size varies from 20-200nm.

What shape is a virus?
The shape of viruses varies greatly. They can be shaped like small balls (spherical viruses) like strands of spaghetti (flexous viruses) rigid rods, like bullets (baciliform viruses) and like geometric shapes (isocohedral viruses) The smallest viruses can be as small as 20nm (20/1,000,000 of a mm) to as much as 2,000 nm for some flexous plant viruses.
What microorganisms are very small and aren't made of cells?
because they arn't as complex as a human cell
Why you need to use a electron microscope to examined a virus?
because viruses are very small and can not seen by any light microscope.only electron microscopes that use electron radiation that have wavelenght about .005 nanometer have enough resolving power to detect such a small particles as viruses

Interferon
Why weren't viruses discovered until about 1935?
The very small size of virus particles was a major limiting factor of the discovery of viruses.
Viruses and bacteria are which type of living thing?
Bacteria and viruses are small and can only be seen through a microscope. The small living things are microorganisms or microbes. Some people do not think viruses are living things because they are acellular particles. They consider them to be an organic structure that interacts with living organisms.
How is an elecron microscope useful?
Its useful to see very small microorganisms & useful to study about small viruses etc.
Bacteria were first seen in 1683 but viruses were not seen until 1938why?
Viruses were too small to be seen in a microscope so they were not identified till the 1930s.
