## T W O FIGURES The Myzothnllophyta, particularly those organisms within the family, Dictyosteliacene, represent remarkable biological material for the study of celluIar differentiation. The life cycles of these forms are now well known, primarily due to the researches of Olive ( '(la), Raper ( '
The cellular slime molds arise by a n aggregation of amocbac, arid the resulting cell mass often will wander some distance over tlie surface of the substratum before rising into the a i r to fruit. The fruiting body consists of a single or branched stalk made up of large vlrcuolate amoebae encased i
Aggregation of Dictyostelium amoebae is inhibited by light. White light intensities >102 laW-cm 2 cause an inhibition which reaches a saturation at 2.103 laW" cm-2. The action spectrum, based on photon fluence -response curves, shows a major peak around 405 nm and extends through most of the visible
