Photosynthesis: In its essence, photosynthesis is the process by which plants make their chemical energy. Most people think that the equation for photosynthesis is the complete process, though there are several steps until the ATP can be made. To produce ATP, light energy must first be captured. Within the leaf, there are two sets of pigments that are responsible for this. The first set is Chlorophyll;> Chlorophyll A which absorbs the yellow-green part of the spectrum> Chlorophyll B which absorbs the blue-green part of the spectrum The second set is Carotenoids;> ß Carotene which absorbs the orange in the spectrum.> Xanthophyll which absorbs yellow from the spectrum. The reason for these pigments is that each pigment can absorb a certain wavelength or group of wavelengths. Without these pigments, these wavelengths would pass through the leaf and their chemical energy would be lost instead of harnessed. Chlorophylls generally absorb the red and blue-violet regions...
