WebApr 5, 2015 · The name comes from the Greek words chloros (green) and phyllon (leaf). There are six types of chlorophyll in nature. The two main types in plants are chlorophyll a and chlorophyll b. Absorption spectra … WebBoth chlorophyll a and b absorb blue and red light wavelengths and reflect green. Chlorophyll a has a peak in the violet and red regions and chlorophyll b in the blue and orange regions. Notice how their absorbance is very low in the green region.

WebFor instance, the light which is not significantly absorbed by chlorophyll a, at 460 nm, will be strongly absorbed or captured by chlorophyll b. The plants can obtain all their energy requirements from the blue and red region of the spectrum, however, there is still a large spectral region, between 500 and 600 nm, where very little light is ... WebFeb 12, 2010 · February 12, 2010. The chlorophyll process is an organic alternative photography process akin to the anthotype process.
