Chlorophyll is then divided into three forms a, b, and c (Campbell, 1996). Chlorophyll a is the primary pigment used during photosynthesis (Campbell, 1996). This pigment is the only one that can directly participate in light reactions (Campbell, 1996). Chlorophyll a absorbs the wavelengths of 600 to 700nm (red and orange) along with 400 to 500nm (blue and violet) and reflects green wavelengths (Lewis, 2004)... displayed 300 characters

Chlorophyll b has only a slight difference in its structure that causes it to have a different absorption spectra (Campbell, 2004). The carotenoid involved with spinach leaf photosynthesis absorbs the wavelengths of 460 to 550nm (Lewis, 2004). The pigments are carotene and its oxidized derivative xanthophylls (Nishio, 2000)... displayed next 300 characters
"The energy of the absorbed photon is transferred from
one chlorophyll molecule to another until it reaches a site called a reaction
center....One oxygen molecule is produced per eight photons absorbed...
This experiment investigated the absorption of different wavelengths of light in chlorophyll a, chlorophyll b and carotene. The aim of the experiment was to create absorption spectra for each photosynthetic pigment chlorophyll a, chlorophyll b and carotene, and investigate any relationship between the absorption of light and the rate of photosynthesis at the same wavelengths, using an action spectrum (School of Biological Sciences, 2006a)...
