A '''tropism''' is a movement or growth in a plant that is a response to a stimulus. It differs from a [[taxis]], which implies [[motility]], or independent movement. Common tropisms include phototropism, which is a response to light, and heliotropism, in which portions of plants such as leaves and flowers turn toward the [[sun]].
