What are 5 facts about viruses?
20 Things You Didn’t Know About Viruses
- Viruses are not alive: They do not have cells, they cannot turn food into energy, and without a host they are just inert packets of chemicals.
- Viruses are not exactly dead, either: They have genes, they reproduce, and they evolve through natural selection.
What are some fun facts about viruses?
- Viruses are not really alive. Viruses operate on the border of life and non-life.
- Viruses survive by hijacking living hosts.
- Viruses evolve faster than any other living organism.
- Viruses can be cooked up from scratch.
- Viruses are beautiful physical objects.
Did virus is a microorganism?
The study of microorganisms is called microbiology. Microorganisms can be bacteria, fungi, archaea or protists. The term microorganisms does not include viruses and prions, which are generally classified as non-living.
How do viruses become microorganisms?
Virus grow only inside cells of other plants and animals, whereas other microorganisms can grow by itself. Other microorganisms have both positive and negative uses, but virus only has negative effects – it causes diseases.

What do microorganisms do?
Microbes are microscopic, single-celled organisms like bacteria and fungi. Although they are often associated with dirt and disease, most microbes are beneficial. For example, microbes keep nature clean by helping break down dead plants and animals into organic matter.
Can a virus reproduce?
There are two processes used by viruses to replicate: the lytic cycle and lysogenic cycle. Some viruses reproduce using both methods, while others only use the lytic cycle. In the lytic cycle, the virus attaches to the host cell and injects its DNA.
What are the four uses of microorganisms?

What are 10 facts about bacteria?
What is a micro-organism virus?
Viruses are acellular microorganisms , which means they are not composed of cells. Essentially, a virus consists of proteins and genetic material-either DNA or RNA, but never both-that are inert outside of a host organism.
Are viruses really microorganisms?
hence they are placed in a different kingdom and not recognised as either of them. Viruses are not microorganisms. Microorganisms produce excretion in the blood. Such excretion contain antibody substance ( poison, virus ). Mocro organisms are living organisms. Virus is the antibody substance, poison.
How are viruses different from other microorganisms?
