Are viruses free-living organisms?

viruses are not technically alive because they cant reproduce by themselves, eat, break down food, or grow


Why are Viruses not considered living by most Biologist?

Viruses are not an organism at all. They are not alive. They are nonliving. They are like cockle burrs that "grab" hold of your clothing or a dog's coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own.


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 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".


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.

Why are viruses not yet consider living thing?

They don't have a Nucleus.


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.

What is the worldssmallest living organism?

Depends on your definition of "living".Viruses, and Nanobes are smaller, but many do not consider them living.Viruses are smallestNanobes are larger than VirusesNanoarchaeum are larger than Nanobes.Nanoarchaeum are considered the smallest aside from Viruses and Nanobes.
