question 39

Multiple Choice

Use the following information when answering the corresponding questions) .
Some plants continually produce secondary defense compounds. Other plants are induced to form secondary defense compou when they are injured. Corn seedling leaves that are chewed on by the caterpillars of a type of cutworm moth emit immediate chemicals LOX products) , and, after six hours, large amounts of terpenoid compounds are released into the air. The terpenoid are released not only from the leaf being chewed, but from all leaves of the plant. The terpenoid compounds attract a parasitoid wasp female that lays her eggs on the caterpillar. When the wasp larvae hatch, they eat and kill the moth caterpillar. T.C.J. Turlings, J. H. Loughrin, P. J. McCall, U. S. R. Rose, W. J. Lewis, and J. H. Tumlinson. 1995. How
caterpillar- damaged plants protect themselves by attracting parasitic wasps. Proceedings of the National Academy of Science

-What can you conclude based only on the information in the preceding paragraph?

• A) Physical injury by the caterpillar mouthparts causes the production of terpenoids.
• B) The parasitoid wasp is attracted by compounds produced by an injured corn plant.
• C) LOX products and terpenoids are the same kinds of chemical compounds.
• D) The attracting terpenoid compounds are always present in the corn seedling.
• E) Chemical signals from the caterpillar saliva attract the parasitic wasp.
