Do plants have allergies?

[Peegee]

That would assume that plants have immune systems.

Plants are also allergic to dinosaurs, Pokemon of the Ice, Bug, Flying, Fire, and Poison elements.

Plants have simple immunity systems. It is mandatory for all organisms to have a sensory system to alert it of .. irritants.

Even single-celled organisms have a rudimentary system for cleaning it out of irritants. However it's so simple that we cannot categorize any of it as an allergic reaction.
