Hi, can anyone explain to me why are the peaks in the action spectrum are wider than the peaks in the chlorophyll a absorption spectrum?

Question

anonymous · Answer

Normally, the peaks of absorption spectrum is a little wider than the action spectrum so that plants can the maximum energy possible. Any diagrams for what you have mentioned?

Yeah I think flowering plants have a preference for different wavelengths at vegetative and flowering phases , most like mainly red for flowering and blue for veg .

I'm not sure why though , anyone else know?

I may be  wrong , I haven't studied plant bio much !

I think it relates to the energy. Sunlight is needed to release electrons from the complexes. Red light has lower energy than blue light.

Peaks in absorption are due to greater photon-absorption by specific photosynthetic pigments, like Shadowys said.
