Changing colours
www.rutgers.edu/news/why-do-leaves-change-color
Leaves change color when chlorophyll – a substance plants use to turn light into sugar that makes a leaf look green – is breaking down and the plant is not rebuilding replacement molecules as the days get shorter. Other pigments, a class called the carotenoids, show as yellow and contribute to the appearance of orange and brown. Carotenoids are always on some level in the leaf, but instead of being overwhelmed by the green as they are in the summer, they appear as the chlorophyll, and thus the green, fades away. The reds are from a more “expensive to make” pigment, anthocyanin, and they develop in fall. The reds and yellow together give us the orange fall colors in some tree species.
