In Order for a Plant to Initiate Chemical Responses to Herbivory

Question

In order for a plant to initiate chemical responses to herbivory
A)the plant must be directly attacked by an herbivore.
B)volatile "signal" compounds must be perceived.
C)gene-for-gene recognition must occur.
D)phytoalexins must be released.
E)it must be past a certain developmental age.

Accepted Answer

When a plant is attacked by an herbivore, it can release volatile organic compounds which serve as "signals" to other parts of the plant to initiate chemical responses. This allows the plant to effectively defend itself against further herbivory.
