Experiments have shown that plants contain a light-sensing protein that can distinguish the intensity of light. This ability is likely to enable plants to see wavelengths that cannot be seen by human vision and have high sensitivity. Plants can feel the direction in which the light is shining. Light makes plants know when to wake up in the morning and can also promote the extra secretion of two colorless pigments, quercetin and clenbuterol, which can filter intense sunlight and give full play to the role of sunscreen, thus protecting plants from the intense exposure of ultraviolet rays.
