| Chemical Control (1) | Similar to nerve control, chemical control coordinates body processes by transmitting messages from one part of the organism to another |
| Chemical Control (2) | Unlike nerve control, chemical control is achieved through hormonal action in both plants and animals |
| Auxins | are one type of plant hormone - influence division, elongation, and differentiation of plant cells |
| Tropisms | are usually adaptive growth responses that enhance the survival of the plant |
| Phototropism | Growth of a plant towards light due to unequal distribution of auxins |
| Geotropism | Growth of a plant due to gravity |
| Endocrine Glands | Endocrine glands synthesize and secrete hormones which control the activities of animals |
| Hormones | are chemicals secreted in one area of the body which affect responses in other areas |
| Metamorphosis | The development in an animal larva that transforms into a sexually mature adult |
