Explanation:
Viruses are not made up of cells and they only contain genetic material like RNA or DNA. since viruses are not made up of cells they do no fit the classification of living organisms. To define living organisms other criterion like reproduction, maintenance of homeostasis and ability to adapt to the external environment are mentioned in the cell theory.
Viruses have the ability to replicate and adapt to even extreme conditions of their environment which makes the question of classifying viruses in the category of living organisms even more complicated.
