How do plant responses to environmental stimuli (tropisms) demonstrate the integration of structure and function?
Question 18 options:

Plant structure remains constant regardless of environmental conditions

Environmental responses only affect plant reproduction, not growth or structure

Plant responses occur randomly without coordination between structure and environment

Growth hormones coordinate structural changes in response to stimuli

Correct answer: Growth hormones coordinate structural changes in response to stimuli.

Explanation: Tropisms (phototropism, gravitropism, thigmotropism) involve hormone redistribution (especially auxin) that causes differential cell elongation on different sides of an organ. That coordinated change in tissue growth alters plant structure (stem bending, root orientation) to improve function (light capture, stability, resource acquisition). The other options are incorrect because plant structure does change with environment, responses affect growth/structure not only reproduction, and responses are coordinated rather than random.
