Viruses - are disease producing agents far smaller than bacteria. They are enclosed in a protein coating which makes them more difficult to destroy.…
On their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply.

Viruses – A viruses is a small capsule that holds DNA or RNA, viruses, unlike bacteria are not self-sufficient and need a ‘host’ in order to reproduce, for example: ‘Human Body’. When a virus enters the body, it enters some certain cells and takes over making them the new ‘host cell’ which makes the parts the virus needs to reproduce, the cells are eventually destroyed through this process. The most common virus is the ‘common cold’ which has no cure.…
Viruses : Visible can only be seen with an electron microscope they can float in the air, sit on a door handle or remain non-living. They become active when they are allowed access to a living cell.…
A virus is a small infectious agent that can replicate only inside the living cells of organisms. Most viruses are too small to be seen directly with a light microscope. Viruses infect all types of organisms, from animals and plants to bacteria and archaea.…
Viruses are made up of proteins and nucleic acids, they aren’t living whereas the others are. Viruses invade cells. They do not breathe or feed.…
A virus is a small infectious agent that replicates only inside the living cells of other organisms. A virus is a small parasite that cannot reproduce by itself. Once it infects a susceptible cell, however, a virus can direct the cell to produce many more viruses. Viruses can infect all types of life forms, such as animals and plants to microorganisms, including bacteria and archaea.…
A virus may not kill a host cell but may become inactive for a period…
Viruses are NOT cells and much smaller than bacteria and damage the cells in which they reproduce.…
Viruses. Is an acellular agent smaller than bacteria consisting mainly of genetic material, that can be active in a close environments ranging from the common cold to AIDS.…

VIRUSES – viruses are smaller than bacteria and can only be seen under a microscope, they can only multiply in living cells. A virus is a simple structure. It is not a cell nor is it living. A virus is simply a coat of protein wrapped around genetic material. Below is an image of a virus and its structure, with labels identifying what a virus is made up off:…
Viruses are a small infectious agent that can only multiply inside the cells of living organisms although unlike bacteria, fungi and parasites viruses are not living organisms. Viruses can infect any living organism such as humans, plants and animals. Viruses multiply by spreading from organism to organism for example viruses can be spread from human to human by coughing or sneezing.…
