Sexual cell division and activation of gametangial cells for conjugation in Closterium acerosum were induced by light. L_<200> cells conjugated at maximum level under the following conditions; (i) a light intensity higher than 1,000 lux in a 16-hr light and 8-hr dark regime and (ii) an illumination time longer than 12 hr at 3,000 lux. L_<200> cells also conjugated under continuous illumination at 3,000 lux. The action spectrum for the activation of gametangial cells had peaks around 450, 611 and 665 nm. 3-(4'-Chlorophenyl)-1, 1-dimethylurea (CMU) inhibited the accumulation of carbohydrates and sexual cell division at 10^<-5> M and the activation of gametangial cells for conjugation at 10^<-4> M.
