1/Nastic Movement: "Nastic movements are non-directional responses to stimuli (e.g. temperature‚ humidity‚ light irradiance). The movement can be due to changes in turgor or changes in growth. Nastic movements differ from tropic movements in that the direction of tropic responses depends on the direction of the stimulus‚ whereas the direction of nastic movements is independent of the stimulus. The rate or frequency of these responses increases as intensity of the stimulus increases. An example of
