What viruses do is they are not living, so they use the cell's life to 'reproduce'. They take all of the cell's nutrition and use that to multiply. Then the cell is dead, and the viruses go on to take over more cells.

∙ 14y agoSince viruses are obligatory parasites they are not considered living. Meaning they can not exist on their on and can only reproduce through invading other living cells and hijacking their ribosomes and organelles to reproduce.

∙ 13y agovirus is an obligate parasite ,means that it has both the living and non-living character.it is mostly dead but when it enters a host cell, it starts generating and becomes alive...When its dead, it is kept safe and used as a chemical.

∙ 13y agoViruses are not alive, they posses all the necessary qualifications to be considered a life form except for one: Viruses cannot reproduce on their own, they need a host cell in order to make copies of themselves.
Wiki User
∙ 12y agoSome scientists believe that viruses evolved out of cells, gradually losing so much of their genetic information that they became dependent on other cells for their reproduction, or alternatively that they arose from bits of genetic material within the cell that acquired a life of their own. Other scientists believe that viruses originated and evolved along with the most primitive forms of life, the simple molecules that gained self-replicating abilities. Some of these took the form of cells - others evolved into the viruses which parasitized those same cells.

Wiki User
∙ 14y agoViruses can only reproduce in a host cell. If viruses evolved first then how were they able to reproduce future generations?
Wiki User
∙ 13y agoSome scientists think that viuses are lliving because they can become living inside a host cell.

∙ 10y agobecause in order to replicate a virus must enter a host cell

Why scientist believe that virus are not living organisms?
viruses do not grow, and viruses do not respond to changes in their environment. Therefore, viruses are not living organisms. All living things reproduce, but Viruses need living cells to reproduce because Viruses cannot reproduce by themselves.
Why don't most scientist consider viruses to be alive?
Most scientists consider viruses as the link between living an non living organisms. Viruses are considered non-living by some scientists because - 1) They donot perform any metabolic activities. 2) Outside the host cell , viruses are present only in crystalised form. (Even after it is un-crystalised , it does not lose it's capacity for infection) 3) It does not require any sort of "food".
Characteristics of livivng and non-living viruses?
viruses are connecting link between living and non-living, as they show only one character of living biengs i.e. reproduction but that too is in inside living host cell otherwise they are consider as nonlivings
Where are viruses on the tree of life?
Many, if not most biologists do not consider viruses living. So, they are not on any phylogenetic tree that I know of. They may have a phylogeny that I am unaware of, though.
Is a viris living?
No. Virologists, the scientists who study viruses, don't consider them living things because they do not meet all the criteria of the definition of life.

Why are viruses not yet consider living thing?
They don't have a Nucleus.
What scientist viruses?
virologist is a scientist that sudies viruses.

Why do you consider viruses as non living outside host?
Viruses either have a strand of DNA or RNA not both like living organisms. They need a host (you and me) in order to replicate.
What type of cell are viruses?
None. Viruses are acellular. Many biologists do not consider viruses to be living things in part because they are acellular. Look at any phylogeny (tree of life). Viruses are not on them.
Viruses and bacteria are which type of living thing?
Bacteria and viruses are small and can only be seen through a microscope. The small living things are microorganisms or microbes. Some people do not think viruses are living things because they are acellular particles. They consider them to be an organic structure that interacts with living organisms.

Do biologists consider viruses living or nonliving?
Biologists consider dormant virions to be non-living because they must obtain a host to function and replicate themselves. However, active viruses are considered to be living, by most scientists.
