Do Viruses Have Different Levels Of Organization?

The biological significance of this article is due in part to the fact that viruses are being considered as partway-living things. Even though they are only halfway living, per se, they are still an important part of the study of living things because of the unique way in which they “live” and continue to reproduce by taking advantage of host cells. The information in this article relates to biologists in that viruses provide an entirely different element of potential life, as they are a cause for reconsideration when it comes to defining and determining life and non-life forms. This

Bacteria is an organism that lives of plants and animals. 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. All viruses have genes made from either DNA or RNA, long molecules that carry genetic information; all have a protein coat that protects these genes; and some have an envelope of fat that surrounds them when they are outside a cell. These are Eukaryotes..when compared to bacteria(prokaryote) and virus.Like plants and animals, fungi are eukaryotic multicellular organisms.

It is often argued whether viruses are living or not. Those who don’t believe that viruses are living generally base their opinion off of the fact that they do not follow the basic definition of “life”. They do not carry out life-sustaining functions on their own like normal organisms. On the other side of the argument, some believe that viruses are in fact, living beings, which is where I rest my opinion.

No, a virus is not a cell because it does not have a plasma membrane, chromosomes, or ribosome (Chivukula,2015). All of these must be present to be considered a cell.

A virus is a small capsule that contains DNA or RNA, viruses, unlike bacteria are not self sufficient and need a host in

Unlike bacteria, that have everything it needs to reproduce, viruses need to use a living cell's organelles in order to replicate.

Viruses are microscopic organisms that can only replicate inside cells of the host organism. Viruses for the most part are so small you would have to use a conventional optical microscope. Viruses can infect any and all types of organisms, such as animals (to include Humans), plants and even bacteria as well as archaea (archaea constitutes a domain or kingdom of single-celled microorganisms). There are millions of different types of viruses. With viruses being believed to be the most abundant type of biological entity, they can be virtually found in every ecosystem on the planet.

One of the most complex and unexplored disease causing agents are viruses. They are known to be able to infect a wide array of organisms, from plants and animals, to bacteria and fungi. Essentially, anything that is living is capable of being infected with a virus. Once the host's cell is infected, the viruses' goal is to produce more viruses which will infect neighboring cells to continue the cycle.

After looking at many articles I believe that viruses are not alive. Even though in the beginning I believed they were. For an object to be alive it needs to have certain characteristics such as being able to: grow, develop, have a purpose, reproduce, adapt, and have cells. A living thing could reproduce which means they would make offspring. Viruses don't have the ability to grow and develop on their own. Viruses don’t have the ability to reproduce on their own without the help of a keeper

There Is another view that contends viruses as living entities. In 2009 David Moreira & Purificacion Lopez Garcia wrote an entry about the reasons why viruses should not be inducted into the tree of life. The main support of their claim is that viruses do not meet the criteria that defines life. Viruses have the same molecular composition as cells: mainly nucleic acids, proteins, lipids, and complex sugars() . In the past this similarity has led scientists to believe that viruses were alive. For many years’ viruses were thought to be the “missing link” (Moreira & Lopez) between the “non-living and the first cells” (Moreira & Lopez). With the discovery of DNA encoding came a theory and definition for what defines life. The theory was based on the fact that all living entities have DNA and evolve. Under these criteria viruses were considered to be living because we know they contain DNA and there has been considerable research showing the ancestral lineage of viruses. This theory survived for many years as the most widely accepted way to describe life. This theory was put to rest in the year 2000 when the International Committee on Taxonomy of Viruses officially concluded that viruses are not alive. This view is still held by many scientists

A virus is an infecting agent. Viruses are non-living they need a living host, a living organism to replicate themselves. When it invades a cell it will implant their code that is capable of copying itself. This will cause a detrimental effect, corrupting the system ti its advantage or complete destruction.

For example, viruses do not use energy and raw materials to grow and reproduce, and they are not made of one or more of the basic fundamental units of life – a cell. Compared to a cell, which includes organelles that enable the structure to grow and reproduce, a virus can only reproduce if another cell is present and that cell has organelles that the virus can inject its own DNA or RNA into and use it for its own replicating or mutating purposes. Viruses are made of a protein coat or capsid with its DNA or RNA genetic material enclosed inside of the capsid. In comparison, in addition to having organelles that use energy to help the cell develop, grow, and reproduce with the help of DNA, the cell by definition is enclosed in a membranous boundary,

A virus is a capsule containing genetic material, even smaller than bacteria. The main task of virus is to reproduce. However, viruses need a suitable host to

Viruses can do many different things to a body, they can destroy, corrupt, and take over cells in the body. They can damage parts of the body or make your body destroy itself, viruses are dangerous but sometimes can be cured. Viruses do not have the enzymes needed to carry out life so

Growth: Viruses themselves do not grow. For true growth to occur, an organism must change and become larger in both size and complexity. When a new virus forms, it is already in its fully developed state, therefore no growth has actually occurred. Instead, what happens is viruses "trick" cells to become host cells that form new viruses, serving as the host cells.
