SYNOPSIS.Chlamydomonas reinhardi has a biological clock regulating phototaxis in dividing and non‐dividing cultures; it also can exert some control on growth of continuous cultures. The period length is ∼ 24 hr; it is temperature‐compensated and not dependent on the average growth rate. The rhythm can be entrained or phased by light‐dark conditions. In dividing cultures a periodic fluctuation in cell number and total protein persists in continuous light.
