Answer 2

Tropism is defined as the movement of a plant or a part of a plant in response to a certain stimuli. Phototropism is defined as the movements of plants in response to sunlight. In this case sunlight is the stimuli.

Negative phototropism is the movement of plant or its part away from sunlight. Such as the growth of roots of a plant deeper inside the ground to absorb nutrients from the soil.
