The movement of leaves of sensitive plants is known as a nastic movement, while the movement of a shoot towards light is known as phototropism.
<h3>What is a Nastic movement?</h3>
A nastic movement may be defined as a type of movement or response of numerous parts of the plants that are significantly independent of the direction of the external stimulus.
The movement of leaves of the sensitive plants is independent with respect to the direction of the external stimulus and thus is known as a nastic movement.
While the movement of a shoot towards light is known as a tropic movement. This type of movement significantly depends on the direction of external stimuli like the direction of light. And hence is known as phototropism.
Therefore, it is the major difference in the movement of leaves of the sensitive plant with respect to the movement of a shoot towards the light.

D. Focusing
Sound waves reflected in flat surfaces like walls, floors and ceilings results to uneven dispersion of sounds by creating locations with high intensity and another with low intensity. This process is called Focusing and can be undesirable in auditoriums.
