Explanation:
A viroid (an infectious RNA molecule) is similar to a virus but not quite the same thing. It's smaller than a virus and has no capsid. A viroid is a coiled, "naked" RNA molecule that can affect a cell. ... Prions (infectious protein particles) have neither DNA nor RNA to transmit infection.
Answer:
A virus is a small infectious agent that replicates only inside the living cells of an organism. Viruses can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea.
where as, Viroid, an infectious particle smaller than any of the known viruses, an agent of certain plant diseases. The particle consists only of an extremely small circular RNA (ribonucleic acid) molecule, lacking the protein coat of a virus. Viroids appear to be transmitted mechanically from one cell to another through cellular debris. Viroids are of much interest because of their subviral nature and their obscure mode of action. Potato spindle tuber disease is viroid-induced. Whether viroids occur in animal cells is still uncertain.
