Viruses are non-living just like a rock is. Since they are not cells, they can not be alive. However, they can "hijack" a living cell. They have either DNA or RNA which allows this hijacking to occur. By doing this, they can make the host cell make more viruses just like them. This causes the virus to spread.

Are there non cellular living organisms?
The closest thing that we have to non cellular living organisms is viruses, and there is some debate about whether they qualify as living things, or should be regarded instead as self-replicating poisons.
What has living characteristics but is not alive?
Viruses have some characteristics of life but these are not considered living organisms as they are non cellular.
Are viruses like parasites?
No; viruses are sub-Cellular 'virons', while parasites are frequently multi-cellular organisms.
What difference between bacteria and viruses shows that bacteria are living organsims and viruses are not?
Bacteria are considered living organisms because they can reproduce, metabolize, and respond to stimuli independently. They have a cellular structure with organelles and can carry out cellular processes. In contrast, viruses are not considered living organisms because they cannot reproduce, metabolize, or respond to stimuli on their own - they require a host cell to replicate and carry out their life cycle.
How do viruses and cellular organisms differ?
Viruses are acellular particles that require a host cell to replicate, while cellular organisms are standalone living entities. Viruses lack organelles and cannot carry out metabolic processes independently. Cellular organisms, on the other hand, have a defined cell structure with organelles and can carry out all life processes independently.
What are properties of viruses?
viruses are non cellular , they have no sexual or asexual reproduction they reproduce by replication
Which of the cellular organisms are attacked by Viruses?
It depends on the virus. Viruses may have a very specific host range.
Are viruses cellular organism?
Yes!!, Viruses are non cellular parasitic agents. They are not included in the classification of organisms. They consist of two parts: and outer capsid(composed of proteins) and an inner core of nucleic acid (DNA or RNA). They can only reproduce inside a living cell.
What are the differances viruses and bacteria?
viruses are non living and bacteria are living organisms
2 reasons why viruses are non living?
Viruses are considered non-living because they lack cellular structure and cannot carry out metabolic processes independently; they require a host cell to replicate and reproduce. Additionally, viruses do not exhibit growth or respond to stimuli in the way living organisms do, as they remain inert outside of a host.
What are the different theories on Viruse?
There are several theories explaining the origin and evolution of viruses, including the regressive hypothesis (viruses evolved from cellular organisms), the coevolution hypothesis (viruses and host cells evolved together), and the escape hypothesis (viruses once were cellular organisms that escaped from cells). The exact origins of viruses remain a topic of ongoing research and debate in the scientific community.
