Question

what is viroid how these viruses infact plant cell . how it differ from animal viruses​

Answer 1

Answer:

Viroids are infectious agents of plants which are similar to virus but consists of only a short single stranded RNA. They are smaller than viruses and lack protein coat.

Viroids are plant pathogens: small, single-stranded, circular RNA particles that are much simpler than a virus. They do not have a capsid or outer envelope, but, as with viruses, can reproduce only within a host cell. Viroids do not, however, manufacture any proteins. They produce only a single, specific RNA molecule.
