According to cell theory, scientists do not classify a virus as living because it does not have cellular structure. Viruses have a simple cellular structure.

Explanation;

-Cell theory states that all living things are composed of one or more cells; a cell is the smallest unit that still retains the properties of life; and new cells only come from cells that already exist.
