The only two ways in which viruses are like organisms is that they can multiply, and that they have similar structure's.
Viruses are not an organism at all. They are not alive. They are nonliving. They are like cockle burrs that "grab" hold of your clothing or a dogs coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These parts can assemble into more viruses and then they breakout of the cell (killing it) and begin the process again. They can not make more viruses on their own.
They are very small and can be considered microscopic. We have to use an electron microscope to see them as they are that small.
Viruses have some, but not all, of the characteristics of living things.
One of the characteristics is they contain genetic material (DNA), which is a characteristic that all living things must have in order to be considered living. And also when inside a host, they are able to reproduce, which all living things must be able to do.
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.
Mutations happen in ALL living things (and also in viruses)!!!!!!
Yes **G1N4** I thought some living things are not organisms, because they are not free living.

One example of things that are similar to living things but do not fit all of the seven criteria of life is viruses. Viruses possess some characteristics of living organisms, such as the ability to replicate and evolve, but they lack cellular structure and cannot carry out metabolic processes on their own. Another example is prions, which are misfolded proteins that can cause infectious diseases, but do not have cells or genetic material of their own. These entities challenge our traditional understanding of life due to their unique properties and behaviors.
"All living things are made of cells" would be a biological observation, and it's only true if we disqualify viruses.

viruses are not considered to be living organisms as they lack the cellular structure and cannot carry out cellular functions on their own. They can only replicate by hijacking the machinery of living cells. Therefore, viruses do not challenge the concept that all living things are made of cells.

Yes, all living things do (as well as viruses, although they force other living things to make them instead of doing it themselves).
No, not all living things contain cells. Viruses, for example, are considered living but are not made up of cells. They are instead composed of genetic material encased in a protein coat.
