circadian rhythm - CIRCADIAN RHYTHM (DIURNAL RHYTHM)
circadian rhythm - Endogenous rhythmic changes that occur in an organism with a periodicity of approximately twenty-four hours when organism is isolated from daily rhythmical changes in its environment. These rhythms are widely demonstrable amongst plants and animals. Examples arc leaf movements and growth in plants, sleep rhythms and running activity in animals. Such rhythms are considered to be a fundamental expression of the ability of plants and animals to measure time although the underlying biochemical and biophysical processes are largely unknown. Circadian rhythms are considered to be a basis of photoperiodism : the two component phases of the circadian rhythm are postulated as skotophile ('dark loving') and photophile ('light loving').
