Virus:-
An infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host is called virus.
Viroid:-
An infectious entity affecting plants, smaller than a virus and consisting only of nucleic acid without a protein coat is called viroid.
Lichens:-
A simple slow-growing plant which typically forms a low crust-like, leaf-like, or branching growth on rocks, walls, and trees is called lichens.
