You have isolated pigments from an unknown plant and are studying their spectral absorption. You irradiate them with a specific wavelength, yet you see no fluorescence. What is the likely explanation?
A)You didn't use the correct wavelength to excite the pigment.
B)They have lost their electron.
C)They are being photoprotected by other pigments.
D)They are experiencing photorespiration.
E)They have passed the photons absorbed to another pigment.
