Autumn is nature’s art show, painting leaves in red, orange, and gold. But why do leaves change color? The answer lies in plant biology and chemistry.
Chlorophyll: The Green Pigment
Leaves look green because of chlorophyll, which helps in photosynthesis. But as days shorten and temperatures drop, trees stop making chlorophyll.
The Colors Behind the Green
- Carotenoids (yellow, orange) and anthocyanins (red) become visible when chlorophyll fades.
- Temperature and sunlight affect the brightness of these colors.
Why Do Trees Do This?
By shedding leaves, trees conserve water and energy during winter.
