Fatty acids that have double bonds within the carbon chain (and therefore fewer hydrogen atoms).
The pigment that traps energy is Chlorophyll.
Chlorophyll is a green pigment commonly found in almost all
plants, algae and cynobacteria. Leaves appear green because they contain this
pigment. This pigment absorbs the light energy from the sun to complete the
process of photosynthesis or food production of plants. Chlorophyll is said to
absorb light in the long wavelength and blue in the short wavelength regions of
the visible light spectrum. Green light is not absorbed, thus making the leaves
of some plants green. Chlorophyll is found at the plant’s chloroplasts, which
comes to have different structures.
