bioluminescence
1. Light produced by certain organisms from the oxidation of luciferins through the action of luciferases and with negligible production of heat, chemical energy being converted directly into light energy. SYN: cold light (1). 2. Any light produced by a living organism. [bio- + L. lumen (-inis), light]

bio·lu·mi·nes·cence (bi″o-loo″mĭ-nesґəns) chemoluminescence occurring in living cells, especially the emission of light as a result of cellular oxidation of a heat-stable substrate (luciferin) in the presence of a heat-sensitive enzyme (luciferase).
