Question

Write three differences between tactic tropic and nastic movement.

Answer

Aspect Tactic Movement Tropic Movement Nastic Movement
Direction of Response Tactic movements are directional, responding towards the stimulus. Tropic movements are directional, responding towards the stimulus. Nastic movements are non-directional, lacking a specific orientation.
Sensory Perception Mechanism Tactic movements typically involve specific sensory organs or structures that perceive the stimulus directly. Tropic movements also involve specific sensory organs or structures that perceive the stimulus directly. Nastic movements often rely on general perception by the plant and do not necessarily involve specialized sensory organs.
Examples An example of tactic movement is geotropism, where plant roots grow towards gravity. An example of tropic movement is phototropism, where plant stems bend towards a light source. Examples of nastic movements include thigmonasty, such as the closing of Mimosa pudica leaves when touched, or nyctinasty, where some flowers open and close in response to the daily light-dark cycle.
