Photobiology (Greek, ‘study of light on life’) is the study of the effect of light upon living organisms. Photosynthesis, the process by which plants convert the energy of light into chemical energy, plays a central role in biology because it is the major energy source in the biosphere. But photobiology is also concerned with phenomena such as light detection, and thus vision, and with the biological production of light (bioluminescence). Most organisms modify their behaviour in response to light and the regular cycle of day and night is an important stimulus for a wide range of periodic phenomena in living systems. RB
