Chlorophyll
Chlorophyll is the primary pigment involved in Photosynthesis, responsible for capturing light energy from the sun. It is located within the Thylakoid membranes of the Chloroplast and exists in several forms, with Chlorophyll a being the most critical for light absorption. This pigment primarily absorbs blue-violet and red wavelengths of light while reflecting green, which gives plants their characteristic color.
Chlorophyll b and other Accessory Pigments complement chlorophyll a by expanding the range of light wavelengths that can be utilized. The energy absorbed by chlorophyll molecules excites electrons, initiating the Electron Transport Chain in the Light-Dependent Reactions. Chlorophyll’s ability to harness light energy makes it fundamental t o converting solar energy into chemical energy in the form of ATP and NADPH.
