Before they fall, leaves often undergo color changes. Chlorophyll, the green pigment needed in photosynthesis, degrades as autumn approaches. Other yellow and orange pigments emerge from leaves as chlorophyll is lost to the environment. Although the green chlorophyll kept these pigments from being seen, they were always present in the leaves. Some leaves also contain red pigments, which when chlorophyll is destroyed also become visible. What causes the fall coloration of green leaves?

Correct! Wrong!

In the passage, it is stated that as autumn approaches, chlorophyll, the green pigment used in photosynthesis, breaks down and is lost from the leaves. As a result, other pigments like yellow and orange, which were always present in the leaves but hidden by the green chlorophyll, become visible. Additionally, some leaves contain red pigments, which also become visible when chlorophyll breaks down. So, the breakdown of chlorophyll is what causes green leaves to change color in the fall.
