Question

In fall, leaves may change from green to yellow or red. Explain in your own words what is happening inside the leaf with regard to plant pigments. ​

Answer 1

The pigment that causes leaves to be green is chlorophyll. ... As chlorophyll goes away, other pigments start to show their colors. This is why leaves turn yellow or red in fall. In fall, plants break down and reabsorb chlorophyll, letting the colors of other pigments show through.
