. Elements of ecology. Ecology. 210 Light illustrate the turning reaction of phototropism by actual growth or by turgor movements. Phototaxis, geotaxis, and other tactic reactions involve the orienta- tion of locomotion toward or away from light, gravity, or some other source of stimulation in the environment. In many instances the turn- ing of the moving organism appears to be due to the unequal stimu- lation of symmetrical sense receptors that control the tonus of the body, leg, or wing musculature.

When the animal moves, it is caused to turn by the unequal posture of its locomotory apparatus. For example, in a positively phototactic animal such as the swimming insect Ranatro, if the left eye receives more light than the right eye, the legs on the left side of the body will be more strongly flexed, whereas the legs on the right side of the body will be more greatly. \^.
