Both the growth of a vine up the trunk of a tree and the directional growth of a houseplant toward a window are examples of tropism responses, which are directional growth responses to environmental stimuli. In the case of the vine and tree, the vine is exhibiting positive phototropism (growth towards light), while in the case of the houseplant and window, the plant is exhibiting positive gravitropism (growth towards the pull of gravity).
