Definitions:

Cyclic Electron Transport

In photosynthesis, the cyclic flow of electrons through photosystem I; ATP is formed by chemiosmosis, but no photolysis of water occurs, and O2 and NADPH are not produced. Compare with noncyclic electron transport.

Noncyclic Electron Transport

In photosynthesis, the linear flow of electrons, produced by photolysis of water, through photosystems II and I; results in the formation of ATP (by chemiosmosis), NADPH, and O2. Compare with cyclic electron transport.

Absorption Spectra

Absorption spectra are the range of wavelengths or frequencies of light absorbed by a substance, each substance having a unique spectrum that can be used to identify it or analyze its properties.

Pigments

Substances that produce color in materials by absorbing certain wavelengths of light and reflecting others, found in nature in plants, animals, and minerals.
