Viruses are not typically considered to be organisms because they are incapable of "independent" or autonomous reproduction or metabolism. This controversy is problematic because some cellular organisms are also incapable of independent survival (but not of independent metabolism and procreation) and live as obligatory intracellular parasites. Although viruses have a few enzymes and molecules characteristic of living organisms, they have no metabolism of their own and cannot synthesize and organize the organic compounds that form them. Naturally, this rules out autonomous reproduction and they can only be passively replicated by the machinery of the host cell. In this sense they are similar to inanimate matter. While viruses sustain no independent metabolism, and thus are usually not accounted organisms, they do have their own genes and they do evolve by similar mechanisms by which organisms evolve.

Which animals are non-living?
All animals are living, but viruses are classified as non-living organisms.
Why are there no cells in chickenpox?
Chicken pox is classified as a virus and viruses are not living things, so they are not classified as cells.
What domain is virus?
Viruses are classified under the domain of "Riboviria," which includes viruses with RNA genomes. Viruses are not considered to be living organisms because they cannot replicate or carry out metabolic processes on their own and require a host cell to reproduce.
Why are viruses classified as non living particles?
They do not reproduce asexually or sexually. Viruses need a host like a cell in order to reproduce. In the dormant state, they are virions, and considered to be nonliving. However, in their active state, as viruses, they are considered to be living organisms.
Why arent virises classified into a kingdom?
Viruses are not classified into any of the kingdoms because they cannot live outside of a host cell (they depend on the host cell's DNA to reproduce and undergo metabolic reactions within it).
Are viruses eukaryotes?
No, viruses are not considered to be eukaryotes. They are non-cellular entities that lack many characteristics of living cells, such as the ability to carry out metabolic processes on their own. Instead, viruses rely on host cells to replicate and survive.
Why aren't viruses classified into a kingdom?
Viruses are not classified into a kingdom because they lack the characteristics of living organisms such as the ability to replicate on their own and carry out metabolic processes. They are considered acellular entities that depend on host cells to reproduce.
Why are virus not living organisms?
They are not classified as living because they cannot replicate DNA or RNA without a host and do not have metabolism with out host. But they can be also classified as a living organism because they have life cycles, and virions that vary greatly in shape, complexity, and size. They are also the most numerous life-forms existing on earth
What kingdom are viruses classified in?
Viruses do not belong to any kingdom. There is an ongoing debate to whether viruses are alive or not. With the facts given, it is up to you to decide if viruses are alive or not. All Living things: -are composed of cells with a complex, organized structure -actively maintain their complex structure and internal environment (homeostasis) -respond to stimuli in their environment -acquire and use materials and energy from their environment and convert them into new forms -reproduce, using the molecular blueprint of DNA -have the capacity to evolve Viruses: -are not made of cells and do not have cells -cannot accomplish the basic tasks of living cells -have no ribosomes to make protein -have no cytoplasm -cannot acquire energy or steal the host's energy -cannot grow or reproduce by themselves or with other viruses -do not respond to stimuli -cannot maintain a stable internal environment -can evolve
What does microbiology refer to?
The study of small, living organisms that are too small to be seen with the naked eye. For the most part, this includes all prokaryotes and the eukaryotes fungi and protists. Viruses are also studied, although they aren't really classified as living.
Why can't we classify a virus as a living thing?
Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.
Why are viruses not classified into any five kingdom?
Viruses are not an organism at all. They are not alive.
