Why do leaves change color.In General, we often see the leaves are green, but when the autumn leaves or dry season turns orange, red or yellow wood species, especially in Western countries, causing the leaves to color change occurs, because it is based on adapting to changing environments. Within each leaf is chlorophyll green or any other color, and has included such as the carotenoid is yellow-orange substances.In the summer, or at regular intervals, we see the leaves are always green, because there is so much sun. Plant photosynthesis can be regularly and when there are many chlorophyll production. Make reflective green plants come out much. See, the leaves are bright green, clearly. But in autumn the temperature decreased, making the plant can not create well like in the summer, chlorophyll. Photosynthesis and thus less carotenoid compounds cause yellow, appear. So we see there are orange or red leaf, yellow.And that cannot be photosynthesis or less photosynthesis so the plant had to reduce power to survive. By salad leaves to reduce energy consumption. For this reason, including when a tree has, therefore, made it the salad leaves, and the leaves are fading down.
