A common example is a plant root growing in humid air bending toward a higher relative humidity level.
positive geotropism (grow in the direction of the force of gravity). Positive phototropism in plant stems. The tropisms of shoots mean that they are likely to grow into the air, where there is light for photosynthesis. The tropisms of roots mean that they are likely to grow into the soil, where there is moisture.Tropisms are controlled by plant hormones called auxins. These water-soluble chemicals move through the plant in solution. Page: 1  1.2  2. 3  3. 4  Next.ositive geotropism (grow in the direction of the force of gravity).
