| Chemical Control | is achieved through hormonal action in both plants and animals |
| Characteristics of Plant Hormones | chemicals that affect growth and development |
| Auxins | are one type of plant hormone |
| Tropisms | adaptive growth responses that enhance the survival of |
| Phototropism | • Growth of a plant towards light due to unequal distribution of auxins |
| Geotropism | Growth of a plant due to gravity |
| Chemical Control in Animals | animals possess cells specialized solely for hormone production |
| Endocrine Glands | • Endocrine glands synthesize and secrete hormones |
| Role of Animal Hormones | • Hormones interact and exert control on metabolic activities |
| Metamorphosis | • The development in an animal larva that transforms into a sexually mature adult |
