Summary Introduction
To describe: The effective defense system in deterring invertebrate herbivores.
Introduction: Plants have developed some defense mechanism to protect themselves from animals. Some plants have modified their leaves to thorns and spines as a part of the defense mechanism. Some plants have developed chemicals to protect themselves from a predator.

Which of the following is an effective plant defense against insect herbivory?
Select one:
a. Hypersensitive response
b. Gene-for-gene resistance
c. Salicylic acid
d. Protease inhibitors
e. Resistance genes
Plants have systemic defense mechanisms (i.e., those that are not normally active but can be induced when the plant is under attack). Briefly describe an example of one systemic defense, including the processes, structures and/or molecules involved.
