Why Do Leaves Change Color In The Fall

Why Do Leaves Change Color In The Fall

For many plants, chlorophyll is the predominant pigment, making them appear green, while red and violet are caused by anthocyanin. When we look at a plant, we see the color green, because it is the part of the light in the visible spectrum that reflects the blue and red color that is absorbed. Due to green chlorophyll, we see green leaves during the summer season, but we also see orange, yellow and red colors in autumn.

The leaves of the plants are responsible for absorbing the light from the sun and converting it into energy for the plant. Some plants seem to have colors like red, but this is not because they do not contain chlorophyll. They do have a lot of chlorophyll, but the green color is dominated by a third type of light-absorbing pigment, which reacts with sugar to produce the red and orange colors we see.

The yellow and orange color of the leaves reveals that chlorophyll, the pigment that makes the leaves appear green, is gradually being lost from the leaf. When chlorophyll begins to fade, we are able to see other colors and pigments on the leaf, especially yellow ones.

The science of changing leaves is a festival of color for the eyes!
