उत्तर
Viruses are living organisms inside a host cell. But the virus is not classified along with bacteria or fungi because they have an inert crystalline structure outside the living cell. They are inert outside their specific host cell and cannot multiply on their own because they lack cellular machinery to use their genetic material.
