In at least some species of plant, a leaf damaged by a caterpillar may __________.
A
produce large quantities of heat-shock proteins that discourage foraging
B
increase the proportion of unsaturated fatty acids in the membranes
C
respond by producing organic solutes that affect water potential
D
increase the synthesis and release of abscisic acid, a deterrent to foraging
E
synthesize and release chemicals that attract wasps that prey on the caterpillar
검증된 단계별 안내1
Understand the context: The problem involves a plant's response to being damaged by a caterpillar. Plants have evolved various defense mechanisms to protect themselves from herbivores.
Identify the options: The problem provides several potential responses a plant might have to caterpillar damage, such as producing heat-shock proteins, altering membrane fatty acids, affecting water potential, or releasing abscisic acid.
Consider the ecological interactions: Some plants have developed mutualistic relationships with other organisms, such as wasps, which can help defend against herbivores like caterpillars.
Analyze the correct response: The correct answer involves the plant synthesizing and releasing chemicals that attract wasps. These wasps are natural predators of caterpillars, thus providing a biological control mechanism.
Conclude with the ecological benefit: By attracting wasps, the plant effectively reduces caterpillar damage, demonstrating an indirect defense strategy that benefits the plant by reducing herbivory.
