PROTOZOOLOGY 



Fig. 59. Mitosis in Trichonympha campanula, XSOO (Kofoid and 

 Swezy). a, resting nucleus; b-g, prophase; h, metaphase; i, j, anaphase; 

 k, telophase; 1, a daughter nucleus being reconstructed. 



cording to Kofoid and Swezy (1919), in Trichonympha campanula 

 (Fig. 59), the prophase begins early, during which 52 chromosomes 

 are formed and become split. The nucleus moves nearer the anterior 

 end where the centriole divides into two, between which develops a 



I
