what is the difference between virus and bacteria?

Answer 1

Bacteria are capable of living alone. Viruses are said to be alive only when inside a living cell.

Bacteria have cell organelles and show life activities. Virus are just a core of DNA or RNA surrounded by a sheath of protein and can only show reproduction while in a living cell.

Bacteria are intercellular organisms( they live in-between cells ). Viruses are intracellular organisms ( they live within/inside cells )

There are many useful bacteria, that help in processes like nitrification and lactification. Viruses on the other hand are always disease causing. In fact, the term 'Virulesence', which is used for a disease causing organism, is derived from the word Virus'

Answer 2

Virus Can Affect Us Really and Really Badly And Bacteria Can Do Too. But The Difference Is That, Bacteria Acts On Organic Matter In Soil Like Dead Bodies Of Animals Insects etc; Which Viruses Can't Do.

Answer 3

The differences between viruses and bacteria are numerous. Viruses are the smallest and simplest life form known. They are 10 to 100 times smaller than bacteria. The biggest difference between viruses and bacteria is that viruses must have a living host - like a plant or animal - to multiply, while most bacteria can grow on non-living surfaces.

Also, unlike bacteria, which attack the body like soldiers mounting a pitched battle, viruses are guerilla fighters. They don't attack so much as infiltrate. They literally invade human cells and turn the cell's genetic material from its normal function to producing the virus itself.

In addition, bacteria carry all the machinery needed for their growth and multiplication, while viruses carry mainly information - for example, DNA or RNA, packaged in a protein and/or membranous coat. Viruses harness the host cell's machinery to reproduce. In a sense, viruses are not truly "living," but are essentially information (DNA or RNA) that float around until they encounter a suitable living host.

Answer 4

Viruses are tiny geometric structures that can only reproduce inside a living cell. They range in size from 20 to 250 nanometers (one nanometer is one billionth of a meter). Outside of a living cell, a virus is dormant, but once inside, it takes over the resources of the host cell and begins the production of more virus particles. Viruses are more similar to mechanized bits of information, or robots, than to animal life.

Bacteria are one-celled living organisms. The average bacterium is 1,000 nanometers long. (If a bacterium were my size, a typical virus particle would look like a tiny mouse-robot. If an average virus were my size, a bacterium would be the size of a dinosaur over ten stories tall. Bacteria and viruses are not peers!) All bacteria are surrounded by a cell wall. They can reproduce independently, and inhabit virtually every environment on earth, including soil, water, hot springs, ice packs, and the bodies of plants and animals.

Most bacteria are harmless to humans. In fact, many are quite beneficial. The bacteria in the environment are essential for the breakdown of organic waste and the recycling of elements in the biosphere. Bacteria that normally live in humans can prevent infections and produce substances we need, such as vitamin K. Bacteria in the stomachs of cows and sheep are what enable them to digest grass. Bacteria are also essential to the production of yogurt, cheese, and pickles. Some bacteria cause infections in humans. In fact, they are a devastating cause of human disease.

Answer 5

First virus has no cure while bacteria can be sensitive to antibiotics.
Virus are self limiting while bacteria are not. Most virus are more virulent than bacteria. And of course their, cellular make up is different from each other.

Answer 6

Bacteria are germs that multiply by splitting into two cells. Those cells keep dividing. While our body contains many good bacteria, there are some that make you sick. They release poisons and cause the body to react to them. If many bacteria grow and the infected person is not immune, they get sick. Bacterial infections are usually treated by antibiotic drugs. Some bacterial infections can be prevented with a vaccine, which creates immunity.

Viruses are simpler in structure than bacteria. They multiply by invading cells and taking them over to make copies of themselves. Viruses make you sick by interfering with how those cells work. Our immune system can fight most viruses. Some viruses can be treated with drugs, but the antibiotics used to treat bacterial infections don't work against viruses. There are vaccines for some serious viral diseases.

Answer 7

A virus (Latin, poison) is a microscopic particle that can infect the cells of a biological organism. At the most basic level, viruses consist of genetic material contained within a protective protein coat called a capsid; the existence of both genetic material and protein distinguishes them from other virus-like particles such as prions and viroids. They infect a wide variety of organisms: both eukaryotes (animals, fungi and plants) and prokaryotes (bacteria). A virus that infects bacteria is known as a bacteriophage, often shortened to phage. The study of viruses is known as virology, and those who study viruses are known as virologists.

Bacteria (singular: bacterium) are microscopic, unicellular organisms. They are often spherical (with the suffix -coccus), rod-shaped (with the suffix -bacillus) or spiral-shaped. They are 0.5-5 µm in the longest dimension, although the wide diversity of bacteria can display a huge variety of morphologies. The study of bacteria is known as bacteriology, a branch of microbiology.

Answer 8

bacteria stay organisms that carry out organic and organic purposes which comprise eating food and expelling waste, among different issues. Viruses do no longer carry out any organic and organic purposes and as a replace comprise in basic terms a single strand of RNA or DNA (no longer the two), enclosed in a protein shell (capsid). it rather is sole function is to invade a suited host cellular, the place it proceeds to close down the cells popular function and as a replace turn the cellular right into a production facility for generating extra virus debris via way of that single RNA or DNA strand.

Answer 9

A bacteria is a living cell capable of doing stuff on its own.

A virus is much much smaller and requires a host, such as a bacteria or animal cells, to live in.

Answer 10

BASICALLY, both are single celled organisms that live as parasites. Bacteria are generally larger than viruses and easier to kill. Viruses are much smaller and harder to eliminate once in the body.
Generally, a viral infection will last longer, and depending on the virus, may not leave until the host is dead.
Whereas a bacterial infection is usually quickly cured with antibiotics.
In the case of meningitis, viral meningitis is better to deal with than bacterial meningitis.
And of course in the case of STD's, who wouldn't rather have
a simple case of the clap or syphillis which are bacteria as opposed to herpes or HIV which are viruses?

And by the way, antibiotics will not affect a viral infection.
Antiviral medication attacks, or inhibits viruses.
