Multiple Choice

Why do leaves appear in shades of yellow,orange,and red in the fall?

A) Cooler fall temperatures change the shape of chlorophyll causing it to absorb different wavelengths of light.
B) The chlorophyll organelles that contain chloroplast pigments breakdown and the leaves reflect more wavelengths of light.
C) In the fall,chloroplasts begin producing enzymes instead of chlorophyll and these reflect different wavelengths of light.
D) Other leaf pigments that were masked by the chlorophyll become visible and reflect wavelengths of light other than green.
E) As the leaves lose chlorophyll,they absorb wavelengths of light that were previously reflected by the pigment.
