|---|
| Phototropism | • Growth of a plant towards light due to unequal distribution of auxins |
| Geotopism | Growth of a plant due to gravity |
| Two Types | Phototropism and Geotropism |
| Chemical Control in Animals | • Chemical control in animals differs from that in plants since animals possess cells specialized solely for hormone production |
| Endocrine Glands | • Endocrine glands synthesize and secrete hormones which control the activities of animals |
| Metamorphisis | • The development in an animal larva that transforms into a sexually mature adult |
| Chemical Control | • Similar to nerve control, chemical control coordinates body processes by transmitting messages from one part of the organism to another |
| Characteristics of Plant Hormones | • Plant hormones are chemicals that affect growth and development |
| Characteristics of Plant Hormones | • These hormones function in the coordination of growth, tropism, and reproduction |
| Characteristics of Plant Hormones | • There are no plant organs specialized exclusively for hormone production |
