A virus usually has a central core surrounded by an outer protein coat called capsid.
Viruses can reproduce only within the living host cells and they are specific to the type of cells they attack.they attack plants through insect vectors or through openings on the plants.
Viruses can affect bacteria by injecting their nucleic acids through the cell wall and into the bacteria cell.such viruses are called bacteriophages.
