What is a virus Class 8?

Viruses are non-cellular, microscopic infectious agents that can only replicate inside a host cell. In a nutshell, a virus is a non-cellular, infectious entity made up of genetic material and protein that can invade and reproduce only within the living cells of bacteria, plants and animals.

What is the 3 virus?

What is Virus short note?

A virus is a parasite that can only be seen under a microscope and can infect living organisms and cause disease. It can make copies of itself inside another organism’s cells. Viruses consist of nucleic acid and a protein coat. Usually the nucleic acid is RNA; sometimes it is DNA.

Is virus a cell?

Because they can’t reproduce by themselves (without a host), viruses are not considered living. Nor do viruses have cells: they’re very small, much smaller than the cells of living things, and are basically just packages of nucleic acid and protein.

Are viruses smaller than bacteria?

Viruses are even smaller than bacteria and require living hosts — such as people, plants or animals — to multiply. Otherwise, they can’t survive. When a virus enters your body, it invades some of your cells and takes over the cell machinery, redirecting it to produce the virus.
