wavelength, nor can the pigment select the wavelength of the light it is to
perceive. Clearly, both have been created for this system to work.

The Miracle that Allows us to Live in a Colorful World

All substances, except wholly transparent ones, absorb light, and
their colors stem from the wavelength of the light they reflect, and which
is not absorbed by the surface in question. Chlorophyll, present in all pho-

tosynthetic cells and a variety of pigments, absorbs all visible wave-
lengths of light except green. This reflected light is what makes leaves ap-
pear green. Black substances absorb nearly all the light that falls on them.
White pigments, on the other hand, reflect nearly all the wavelengths of
light that strike them.

c) Leaves appear green because
green light is reflected back by the
chlorophyll, while other wave-
lengths are absorbed.
