Difference between autonomic and paratonic movements in plants?

Question

I can't understand the difference be because both involvery the main cause that is an external stimuli, so how do they differ(

Answer 1

I believe you might be referencing tropic movement instead of paratonic. The difference between the two is as follows:

1. Autonomic Movement (Autotropism): Autonomic movement, also known as autotropism, refers to the spontaneous or automatic movements in plants that are not in response to external stimuli. These movements are often related to growth and development. For instance, the growth of roots and stems towards gravity (geotropism) or away from light (phototropism) are examples of autonomic movements.
2. Tropic Movement (Tropism): Tropic movements, or tropisms, are plant movements in response to external stimuli such as light, gravity, water, or touch. Tropisms can be either positive (movement towards the stimulus) or negative (movement away from the stimulus). Examples include phototropism (growth towards light), geotropism (response to gravity), hydrotropism (response to water), and thigmotropism (response to touch).
