nonliving A virus is a submicroscopic obligatory parasitic particle that infects cells in biological organisms. Viruses are non-living particles that can only replicate when an organism reproduces the virulent RNA or DNA.
Viruses are submicroscopic entities capable of causing disease. They are a piece of nucleic acid (genetic material) surrounded by a protein coat. Once inside the plant cell, the nucleic acid portion directs the plant cell to produce more virus nucleic acid and virus protein, disrupting the normal activity of the cell.iruses are submicroscopic entities capable of causing disease.
