the tendency of plants to grow toward or away from light, influenced by the direction and intensity of light
Example
The tomato seedlings displayed positive phototropism as they grew towards the nearby window.
The leaves of indoor plants showed negative phototropism by curling away from direct sunlight.
Farmers use knowledge of phototropism to optimize crop placement for maximum sunlight exposure.
Sunflowers exhibit phototropism by turning their heads to face the sun throughout the day.
Plant biologists study phototropism to understand how plants perceive and respond to light stimuli.
