Viruses are known to be acellular as they do not have cellular structure. they do not have most of the cellular components i.e they dont have
Plasma membrane
ribosomes
although viruses consist of nucleic acids, proteins,lipids and carbohydrates but they dont have the ability to perform and function and divide unless they enter any other living host cell. viruses uses the machinery of the living host cell and without the cells viruses are unable to divide.
