Bonnie teaches us about phototropism and why plants need light.
- Plants movement towards sunlight, known as phototropism, is a remarkable phenomenon, and it involves the detection and response to variations in sunlight intensity and direction.
- A plant’s core sensors are responsible for detecting sunlight changes, and when activated, trigger growth responses necessary for each plant.
- Plants bend and adjust to outcompete neighbours, crucial for thriving in various environments.
- Sunflower fields showcase phototropism very well, as blooms turn to face and track the sun's movement over the course of a day.
- Plants are intelligent and strive to optimise photosynthesis and energy production by capturing maximum light.
- Phototropism contributes to the ecosystem balance by influencing plant competition for sunlight.
