Viruses are not classified as living, while cellular organisms are. Viruses are essentially a protein case with mRNA inside. Cells are far more complicated.
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.
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.
Viruses are thought to have evolved from ancient cellular organisms, possibly derived from genetic elements that "escaped" from cells. It is believed that viruses originated billions of years ago and have co-evolved with their hosts, adapting to exploit different cellular mechanisms for replication and survival.
Viruses lack the cellular machinery for metabolism and reproduction on their own, which are key characteristics of living organisms. They can only replicate by hijacking host cells. Therefore, viruses are considered more like particles than living organisms.
No, viruses do not have organelles because they are not considered living organisms. They are made up of genetic material enclosed in a protein coat and rely on host cells to replicate. Viruses lack the cellular structures and functions that define living organisms.
No; viruses are sub-Cellular 'virons', while parasites are frequently multi-cellular organisms.
It depends on the virus. Viruses may have a very specific host range.

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.

Viruses have some characteristics of life but these are not considered living organisms as they are non cellular.
Multi-cellular I think although I am not 100% sure. Please do not take my word for it. Hope this helps...

Viruses do contain genetic material and a protein coat, but they lack the cellular structure found in living organisms. They are considered to be organized structures, but they are not considered to be living organisms due to their dependency on host cells for replication.
