Answer 1

The main difference between tropic and nastic movement is that the direction of the tropic movement depends on the direction of the stimulus, but in contrast, the direction of the nastic movement is independent of the direction of the stimulus. Furthermore, tropic movement is a growth movement while nastic movement can be either a growth movement or change in the turgor. For example, stimuli such as gravity, oxygen, chemicals, electric filed, etc. result in tropic movements. Meanwhile, the stimuli such as temperature, humidity, light irradiance, etc. result in nastic movement. In brief, tropic and nastic movement are two types of paratonic movements occurring in response to various external stimuli. Generally, both types can alter the growth pattern of the plant.
