A change in a plant’s growth in response to external factors, like growing towards the light
Real World Example
Imagine trying to find your way in a dark room, guided only by the faint glow of a nightlight. Just like you instinctively move towards the light to help navigate and find your way out, plants grow towards the light to optimize their ability to photosynthesize, which is essential for their survival. In both scenarios, whether it’s a person seeking illumination in darkness or a plant stretching towards sunlight, the external cue (the light) triggers a directional movement to maximize benefit – clarity in the room for you and energy for the plant.
