108 BIOLOGY: GENERAL AND MEDICAL 



minute cells or spores arise through the division of one 

 large one, the chromosome formation and nuclear spind- 

 les are theoretically present but not actually visible. 



In morbid conditions the process of cell division may 

 miscarry in a variety of ways. Thus, in the event of the 

 separation of the nuclear material being imperfect and 

 incomplete, a large lobulated nucleus may be formed; in 

 case the nuclear divisions are completed without accom- 

 panying division of the cytoplasm, giant cells may be 

 formed.
