After studying this chapter, you should be able to accomplish the following outcomes.
Plant Hormones - Explain the role of hormones when plant cells utilize signal transduction as a means to respond to stimuli.
- Compare and contrast the effects of auxins, gibberellins, cytokinins, abscisic acid, and ethylene on plant growth and development.
Plant Responses- Show that gravitropism, phototropism, thigmotropism, turgor movements, and sleep movements are responses to particular stimuli.
- Distinguish between a circadian rhythm and a biological clock.
- Relate photoperiodism to flowering in short-day/long-night plants and in
long-day/short-night plants.
- Describe ways in which plants respond to their biotic environment, including physical barriers, chemical toxins, systemic mechanisms, and relationships with animals.
- Give examples to show that the chemical defenses of plants make good medicines for people.
