Tropism is a directional growth response of a plant to an external stimulus. The plant grows towards or away from the stimulus. Examples include: Phototropism*: Growth in response to light. Shoots typically grow towards light (positive phototropism). Gravitropism* (or geotropism): Growth in response to gravity. Roots grow downwards (positive gravitropism), and shoots grow upwards (negative gravitropism). Thigmotropism*: Growth in response to touch, seen in climbing plants. 4 done, 1 left today.
