Graduate Botany

Why do some leaves change color (red, yellow, orange, etc.) in the fall?
  1. The chlorophyll molecule is modified to absorb different wavelengths of light.
  2. The chlorophyll molecule breaks down and other pigments now become visible.
  3. Because the leaves are dead.
  4. Cold weather denatures the chlorophyll molecule and it begins to reflect different colors.
