Biological pigments are molecules that preferentially absorb light at particular wavelengths. ... The chlorophyll molecules absorb photons and funnel the energy ...
Photosynthesis is the source of most organic carbon on Earth, as well as the oxygen in the air. The overall chemical equation for oxygenic photosynthesis is:

Mar 14, 2017 · Plant leaves preferentially absorb red and blue wavebands, while the green region of incident light is absorbed less (Fig. 3). Approximately ...
Terrestrial green plants absorb photosynthetically active radiation (PAR; 400–700 nm) but do not absorb photons evenly across the PAR waveband. The spectral absorbance of photosystems and chloroplasts is lowest for green light, which occurs ...

Chlorophylls absorb photons within narrow energy ranges. Two kinds of chlorophyll in plants, chloro- phylls a and b, preferentially absorb violet-blue and red.

One function of carotenoids is to absorb light in wavelengths that chlorophyll is inefficient at absorbing, such as the blue-green to green wavelengths.
It's sometimes hard to remember that the beauty we see in fall colors is the result of the death of a tree's leaves. That there can be such joy in celebrating the death of something is a curious aspect of life worthy of a philosopher's attention. But even without the philosophical implications, we can learn much about life by studying death. In fact, when you think about in the larger context, every essay about fall colors is about death in some form. Today's essay is no exception. It focuses on the simple question of why some turn yellow and orange before they fall off and die.

chlorophyll preferentially absorbs light around wavelengths of 430 nm (blue) and 660 nm (red). Green light, in contrast, is absorbed poorly by this pigment.
