Non-photochemical quenching

Definition

Non-photochemical quenching is a protective mechanism that plants employ to dissipate excess light energy. Plants often absorb more light energy than they can process in photosynthesis, and the quenching of singlet excited chlorophylls - non-photochemical quenching - leads to the harmless dissipation of this excess energy as heat.
