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.
because they arn't as complex as a human cell
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.
Viruses cannot be seen under a light microscope as they are too small. However, techniques like electron microscopy and immunofluorescence can be used to visualize viruses. By tagging viruses with fluorescent markers or using more powerful electron microscopes, researchers can study viruses in greater detail.

No, viruses are not made of cells. They are small infectious agents that can only replicate inside the living cells of organisms. Viruses consist of genetic material (DNA or RNA) enclosed in a protein coat called a capsid.

Viruses are too small for van Leeuwenhoek to have seen with his simple microscope.
Viruses are too small, and can't be seen in an optic microscope.

The very small size of virus particles was a major limiting factor of the discovery of viruses.

Viruses are too small to be seen directly with a light microscope.Can be seen when it's examined under an electron microscope
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.
Its useful to see very small microorganisms & useful to study about small viruses etc.
yes because when you play the music on sound cloud that others uploaded you download what viruses are on theyere computer
There are thousands of different types of viruses that exist in the world. These viruses can infect various organisms including animals, plants, and bacteria. It is estimated that only a small fraction of all viruses have been identified and studied so far.
