These are the differences between viroids and viruses: - Unlike viruses, viroids cause plant disease. - Unlike viruses, viroids do not encode proteins. - Viroids only consist of nucleic acid without a protein coat. - Viroids are also smaller than viruses
Explanation:Viroids are free RNA molecules of low mass with none macromolecule coat whereas viruses will have either RNA or deoxyribonucleic acid molecules encapsulated during a macromolecule coat. Viroids are smaller in size than viruses. The virus is associate obligate living thing parasite which may reproduce solely by offensive and usurping host cells as they lack the cellular machinery for a replica. A virusoid is sub infectious agent, smallest agent of an infectious disease.
