A virus is a parasitic organism that attaches to a bacteria and multiplies by taking it's sustenance from the bacteria. It fulfills the basic definition of life to biologists: It has the ability to replicate itself. There is still debate over this, but most scientists believe viruses are living entities, though some describe them as being "at the edge of life". Vaccines to prevent infection by certain viruses fall into two types: live vaccine and dead vaccine. Vaccines are made from the virii themselves. Logically, you cannot make a live vaccine from a non-living thing. There is an even smaller, less understood relative of viruses called a "viroid", which is not well understood as of yet.
Viruses have some, but not all, of the characteristics of living things.
No, non-living things do not have the ability to reproduce. Reproduction is a biological process that involves the creation of new individuals from existing ones, and non-living things lack the necessary biological mechanisms for reproduction.
Yes **G1N4** I thought some living things are not organisms, because they are not free living.
Viruses lack the ability to replicate on their own, relying on host cells to reproduce. This autonomous replication is a characteristic of all living organisms, but viruses require a host for this process. Therefore, this is a property of all organisms, but not of viruses.
No, not all living things have cells. While all living things are made up of cells, some organisms like viruses are considered living but do not have cells. Instead, viruses are composed of genetic material (DNA or RNA) enclosed in a protein coat.
Viruses depend on living cells because they reproduce inside of them.

viruses are nonliving things. but they need living things to reproduces. so live
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.
Viruses are things that spread and contain germs. An Organism is a living thing.

They reproduce.
A virus lacks key characteristics of living organisms, such as the ability to reproduce on its own and the presence of cellular structure. Viruses are considered as biological entities that require a host cell to replicate and carry out their functions. This dependency on a host cell is a key reason why viruses are not classified as living things.
Viruses aren't living, and are the only non-living organisms, and bacteria are prokaryotes, meaning they don't have a defined nucleus.

viruses are non-living yet they can grow and spread through bodies
Anything living. Since viruses are not living (they don't have cells) they don't count.
