In order to spread, Tobacco Mosaic Virus (TMV) must infect healthy plant cells. Which statement below is true?

Plants are host cells that supply the machinery for making copies of TMV.

Plants are hosts because they lack nuclear membranes for the virus to attack.

TMV thinks plant cells are simple cells that can easily be attacked compared to human cells.

Plants are not affected by TMV because they have strong immune systems.
