Action Spectrum

A graph of the effectiveness of light at specific wavelengths in promoting a light-requiring reaction. Compare with absorption spectrum.

Absorption Spectrum

A graph of the amount of light at specific wavelengths that is absorbed as light passes through a substance. Each type of molecule has a characteristic absorption spectrum. Compare with action spectrum.

Carotenoids

A class of pigments found naturally in plants, algae, and photosynthetic bacteria, important for photosynthesis and providing coloration.
