Why trees lose their green color in autumn
Why do certain trees lose their green color in autumn season?
Expert
In autumn, the days become shorter and nights longer therefore there is a drop of the photosynthesis rate and certain plants prepare themselves for the winter forming nutrient stores. In this procedure, nutrients from the leaves travel in the direction of storage sites: trunk, limbs and roots. With less chlorophyll generated in leaves the typical green color of the plant fades.
