Did You Know:
The green color of leaves is due to chlorophyll, the pigment responsible for capturing sunlight. In the fall, as chlorophyll breaks down, other pigments like carotenoids (which produce yellow and orange colors) become visible.
Leaves can change color based on environmental conditions. For instance, in autumn, cooler temperatures and shorter days cause some leaves to change from green to vibrant yellows, oranges, and reds. πβ¨πππ
