Tropisms: Phototropic, Geotropic and Thigmotropic Plant Growth

WebPhototropism—the directional bending of a plant toward or away from a light source—is a response to blue wavelengths of light. Positive phototropism is growth towards a light source (Figure 2), while negative phototropism (also called skototropism) is growth away from light. Figure 2. WebThis change in the growth pattern in response to a stimulus is known as tropism. Unlike animals, the response of a plant is regulated by the interaction of two or more plant hormones.
