What is an example of a non-living thing made up of cells?

I remember in grade 8, we studied cells and we examined cork under a microscope. Corks contain cells, but is a non-living object.

The cell is the basic unit of living organisms. Since non-living things are not made of cells, the number is irrelevant.

A non-living thing made up of cells is a virus. Viruses are microscopic infectious agents that consist of genetic material (DNA or RNA) enclosed in a protein coat called a capsid. They cannot replicate independently and require a host cell to reproduce. While viruses possess genetic material and exhibit some characteristics of living organisms, they lack essential cellular machinery and metabolic processes to be considered fully alive. To find this answer, you can search for "example of a non-living thing made up of cells" or "what are viruses" using an internet search engine or consult relevant biology resources.
