What Statement Below Characterizes Pigments' Function

Question

What statement below characterizes pigments' function?  
A) They absorb some photons.
B) They reflect all photons.
C) They absorb photons of all colors.
D) They absorb photons of all wavelengths.
E) They absorb ultraviolet wavelengths.

Accepted Answer

Pigments have the primary function of absorbing certain wavelengths of light while reflecting or transmitting others. This absorption of photons by pigments helps to initiate chemical reactions, such as photosynthesis in plants, or changes in color in animals. Therefore, choice A, which states that pigments absorb some photons, is the correct statement. Choices B, C, D, and E are incorrect as they suggest that pigments reflect all photons, absorb photons of all colors, absorb photons of all wavelengths, or absorb only ultraviolet wavelengths, none of which are accurate characterizations of the function of pigments.
