How Does Chlorophyll Affect The Decline Of Plants

The reason leaves often change colors when the weather gets colder, before dropping off of trees is because leaves are colored by pigments. In autumn, when it starts to get cold, the leaves start to change their pigment making other colors. Heavy wind and rain can cause leaves to fall off of trees before they are already colored. The reason the fall solo is because the chlorophyll in the leaves break down and the green color in the leaves disappears do to the weather changing. Chlorophyll is what gives leaves their green color. In the fall, cooler and shorter days make an end to auxin production. This allowed for the layer tp grow and to cut off the circulation of water. When this happens, chlorophyll falls apart and quickly. When there's less sun, athocyanin isn't really chemically active and the leaves are more orange, yellow and red. …show more content…
As the days get shorter, leaves start to not be able to make as much chlorophyll which gives the leaves the green color. That's why all we see in the summer on leaves is green, because chlorophyll overpowers the other colors. High heat also can take away a leaves color and can cause them to drop earlier. The tree has to seal the spots where the leaves have grown, or else it will die. An extreme drought in the summer can delay somewhat the changing of the colors in fall. During the growing season, chlorophyll is constantly being broken down produced and broken down, and then the leaves appear green. How the leaves during the winter time/fall change, there is not enough light or water for photosynthesis. Then the green chlorophyll disappears from the leaves. Then in the fall, sunlight, and cooler nights in in Autumn cause leaves to turn glucose into a red color. The brown color of leaves is made from waste left in the
