SUMMARY 



1. In Monas a reduction of the temperature brings about certain structural 

 changes within the cell that result in the formation of many small spores, each of 

 which has the power of reproducing the organism. 



2. It is thus possible by means of variation in the temperature to control the 

 methods of reproduction in Monas. At a temperature of 20° C. Monas multiplies 

 sexually and by simple fission. At a temperature of 1° to 4° C, reproduction by 

 asexual spores takes place.
