Viruses do not have all of the characteristics of living things. They consist of a protein coat which contains either DNA or RNA. They are not made of cells. They have no cellular structures. They do not require nutrients. They do not have metabolism. They do not grow or develop. They do not reproduce on their own. They must high-jack a living cell, inject it's genetic material, which then takes over the host cell which then becomes a virus factory. Eventually the cell becomes so full of replicated viruses that they burst, releasing the viruses so they can go on to attack other cells.
A virus is not considered a living thing because it can't live on its own and has to rely on another animals cells to reproduce. A living organism technically has to be able to survive and reproduce on their own without help from other organisms. They don't use their own energy to grow, make food, take food, or produce waste.
Viruses are not considered living organisms because they are not composed of cells (the Cellular Theory of Life). Also, viruses cannot replicate independently - they must infect a living cell before their structure and genetic material can be reproduced and multiplied.
However, there is a vigorous ongoing debate about whether or not viruses are living - they do have discrete genetic material that is transmitted from "parent" to "offspring", they can react to the environment by changing what proteins they are expressing and some viruses are extremely complex.
One of the main reasons viruses are considered non living is because they cannot replicate by themselves. In order to replicate they must find a host cell and inject DNA into the host cell which disrupts the host cell's normal processes by causing it to make copies of the virus instead of carrying out all its normal processes. Once the viruses have been created inside the host cell, the host cell bursts to release the viruses. This is the same reason it is considered parasitic, since it uses the host cell for its benefit and damages or kills the host cell in the process.

MaxineViruses lack the key characteristics of living organisms, such as the ability to replicate on their own, grow, and metabolize. They require a host cell to reproduce and are not capable of carrying out cellular processes independently. Therefore, they are considered biological entities rather than living organisms.
Viruses lack some features that are considered typical of living beings. While they can reproduce, they don't move, they have no metabolism, and their reproduction is carried out by the host cell, not by themselves. When they are not in the process of infecting a cell, they are inert like any crystal.

Do some non living things have characteristics of living things?
Yes, some non-living things, like viruses, exhibit characteristics of living things such as replication and evolution. However, they are considered non-living because they cannot carry out these processes on their own and require a host cell to reproduce.
Are all organisms living things?
Yes **G1N4** I thought some living things are not organisms, because they are not free living.
Do all living things have cells?
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.
Can non-living things reproduce?
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.
Viruses have some of the properties of living organisms which is a characteristic of all organisms but NOT of viruses?
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.
