What: "The energy that the carotene picks up from the light it absorbs is transferred to the chlorophyll to help it do its job in photosynthesis. Thus carotene is like an assistant energy gatherer. Unlike chlorophyll, however, carotene is more stable and, when chlorophyll dies out in the fall, the carotene remains and the leaf is yellow."
