Detailed explanation-1: -Tropic movement is the movement of plant or parts of a plant in response to environmental stimuli.

Detailed explanation-2: -The response of an organism, usually a plant, to an environmental stimulus is called a tropism. Some common plant stimuli include light, gravity, water, movement of the sun, and touch. The naming of the tropism is associated with the stimulus.

Detailed explanation-3: -Tropisms can have a sign: positive if the plant grows toward or in the direction of the stimulus or negative if it moves away from the stimulus.

Detailed explanation-4: -There are 6 known types of tropic movement observed in plants. They are: Phototropism, Gravitropism, Chemotropism, Thigmotropism, Thermotropism and Hydrotropism.

Detailed explanation-5: -Nastic movements are plant movements that occur in response to environmental stimuli but unlike tropic movements, the direction of the response is not dependent on the direction of the stimulus.
