What is the difference between a virus and a bacteria?

Answer 1

The main difference between viruses and bacteria is that viruses are packets of genetic material and cannot survive on their own, while bacteria are single-celled organisms that can. Bacteria take in nutrients, expel waste, grow, and reproduce (multiply). Viruses need a host cell (a bacterium, or a plant or animal cell) in order to reproduce copies of itself and have no need to feed or grow in the typical sense. In fact, many argue that viruses are not living entities, just bits of genetic material and cellular machinery.

A bacteria is a cell, with its own metabolism, which can act independently of a host cell. A virus is composed of some form of nucleic acid (either DNA or RNA) with or without some form of protein envelope; it has no metabolism of its own and can only be biologically active inside the cell of some other organism, and takes over its host cell's cellular machinery.

a virus and a bacteria are also different by a bacteria is worse than a virus and that a bacteria spreads and a virus usually doesn't.

13 sentences about how is bacteria different from virus:

1.Virus is a nonliving thing.

2.Virus don't have cells.

3. Bacteria can be good for you.

4. Virus only does 2 basic functions.

5. Bacteria can be killed by antibiotics.

6. Bacteria can be seen in normal microscope.

7. Bacteria is a living thing.

8. Bacteria is unicellular.

9. Virus never can be good for you.

10. Virus never can be killed.

11. Virus only can be seen in a hard microscope.

12 Bacteria is sometimes harmful.

13. Virus only binds to a specific host cell and is only harmful to that specific cell.

One major difference between viruses and bacteria is the method of reproduction. Bacterium is a completely self-contained and self-reproducing unit. When the time is right, bacterium will split its DNA and RNA genetic material in two. Separate cell walls will build up around these two new bacteria, and this process will continue until thousands or millions of bacteria have formed. This is how strains of bacteria survive in almost every environment on Earth, including non-living surfaces like rocks or plastic. A virus, on the other hand, cannot reproduce without a living host. A may lie dormant for thousands of years before finally coming into contact with a suitable host. Once it enters the body of a host, a virus uses leg-like appendages to clamp onto a cell and a spike or chemical coating to penetrate the cell wall. Once inside a living cell, a virus replaces the cell's original DNA or RNA commands with its own genetic instructions. Those instructions are usually to make as many copies of the virus as possible. Once the individual cell has outlived its usefulness, it explodes and sends out thousands of copies of the original virus to other unsuspecting cells.

Answer 2

A virus, which is the simplest form of a genetic entity, is incapable of life and reproduction outside the cells of other living organisms. A virus contains genetic material (DNA or RNA) but has no ribosomes. Although some viruses are not harmful, many harm their host organism by destroying or altering its cell structures. Generally, the body perceives viruses as antigens and produces antibodies to counteract the virus.

Bacteria are organisms with a full cellular structure (prokaryotes). They, too, can be not harmful or harmful. Harmful bacteria are perceived as antigens by the body, which in turn produces antibodies. In some cases Infectious Diseases may be treated effectively with antiseptics, which are chemicals that oxidize inactivate the infecting organism (like Lysol or Chlorox). Antibiotics are effective in treating bacterial infections, sometimes working by destroying bacterial cell walls or by inhibiting bacterial creation of DNA, RNA, or proteins. Antibiotics are ineffective in treating viral infections.

Answer 3

Bacteria are living organisms and can be fought off or killed with antibiotics.

Viruses are non-living particles that cannot be fought of or killed with antibiotics. the B cells in your body make antibodies witch are used to fight of viruses.

Answer 4

bacteria are living organisms; viruses are not
