WebPhotosynthetic pigments within the photosynthetic membranes are organized into photosystems, each of which is composed of a light-harvesting (antennae) complex and a reaction center. The light-harvesting complex consists of multiple proteins and associated pigments that each may absorb light energy and, thus, become excited. WebOct 23, 2024 · Chloroplasts have other accessory photosynthetic pigments, such as carotenoids, that are of two types: Carotenes (orange) Xanthophyll (yellow) Carotenoids absorb different wavelengths of light than chlorophyll. Thus it expands the spectrum of light that provides energy for photosynthesis. sbtb season 4 # 24WebSolution. The most abundant plant pigment in the world is chlorophyll a. Chlorophyll a is the most important photosynthetic pigment because it is directly involved in the conversion of light energy (photons) to chemical energy. Chlorophyll a absorbs light with wavelengths of 430nm (blue) and 662nm (red). It reflects green light strongly so it ... sbtb season 4 # 5

"WebApr 24, 2024 · The importance of pigment in photosynthesis is that it helps absorb the energy from light.
