Bacteria is passed by touch

virus is in the air

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.

To start ( this is all I remember), bacteria can reproduce themselves, because they have their own DNA protein chains. virii (viruses, proper Latin form) have to get into the host cell ( the cell fo the animal it infects) to borrow the DNA, using its RNA protein code. So, bacteria self-reproduce, virii use the host to reproduce. This may have something to do with the fact that we can treat bacterial infection with antibiotic, but not a virus. So, the common cold is usually a virus, and we can't kill it. Similarity- each one is tansmitted different ways- some are only through blood, some are only by contact (saliva, skin, touching something the sick person touched) and some are airborne.

>bacteria - a single-celled, often parasitic microorganism without distinct nuclei or organized cell structures. Various species are responsible for decay, fermentation, nitrogen fixation, and many plant and animal diseases.

>virus - submicroscopic parasitic particle of a nucleic acid surrounded by protein that can only replicate within a host cell.
Viruses are not considered to be independent living organisms.

A bacteria is a single celled organism that replicates itself through cell division. Most antibiotics hinder these cells' ability to build cell walls and thus replicate

A virus is a much smaller particle that consists of genetic material in a structure. The virus is typically found within a host cell, where is utilizes the cells reproduction system to create multiple copies of itself, killing the host cell.

Bacteria can reproduce on its own. Bacteria is undoubtedly alive. A virus needs a host to inject its DNA into in order to replicate itself. Since a virus cannot reproduce on its own there is some debate as to whether a virus is to be considered "alive" or not.

Bacteria are unicellular organisms with a nucleus and generally complete set of organelles and can live independently in a variety of environments. Viruses do not have a nucleus and rely on the host's cellular reproduction mechanisms to multiply. They generally function by attaching themselves to the wall of a host cell, injecting their RNA into the cell, and instructing the cell's DNA to make copies of the viral RNA, producing more viruses.

virus isnt considered a living organism. Virus needs other cells to produce.

bacteria can be fought with and cured with antibiotics but virus stay in your body till your body can fight them off...virus can not be fixed by antibiotics or paralyzed for a while.

Primarily, there are 2 differences

1.) bacteria are living creatures, whilst viruses are "prions"
2.) Bacteria is solely responsable for causing FARTS, whilst viruses are completely unentertaining
