What portion of the electromagnetic spectrum is most absorbed by the chlorophyll pigments in the thylakoid membranes?
nadya68 [22]

Answer: The visible part of the electromagnetic spectrum, <u>specifically blue and red wavelength</u>

Explanation:

Let's begin by explaining that pigments generally absorb more light than they reflect (they absorb certain wavelengths and reflect others). Therefore, the color that a given object seems to have depends on which parts of the visible electromagnetic spectrum are reflected and which parts are absorbed.

In this sense, in the thylakoid membranes there are two types of <u>chlorophyll pigments</u>:

-clorophyll b that absorbs the blue light of the electromagnetic spectrum

-clorophyll a that bsorbs the red light of the electromagnetic spectrum

That is why we generally see plants in green color and not in other colors.
