What Portion Of The Electromagnetic Spectrum Is Most Absorbed By The Chlorophyll Pigments In The Thylakoid Membranes?. Chlorophyll is the green pigment found in all plants and it absorbs light most strongly in the blue portion of the electromagnetic spectrum, followed by the red portion. What portion of the electromagnetic spectrum is most absorbed by the chlorophyll pigments in the thylakoid membranes?

The photons of light absorbed by chlorophyll cause a displacement of 2 electrons to a higher energy level which reduces a cytochrome in an electron transport chain in the thylakoid. The visible part of the electromagnetic spectrum, specifically blue and red wavelength. Chlorophyll is the green pigment found in all plants and it absorbs light most strongly in the blue portion of the electromagnetic spectrum, followed by the red portion.
