amitosis.

(b) Criticism of previous opinions : — The vital processes of the cell 
depend on interactions between nucleus, protoplasm, and outer world. 
“ The physiological import of the nucleus depends solely upon its meta- 
bolic relations to the rest of the cell. Only by these metabolic relations 
does it exert an influence on the functions of the cell and enter into its 
life.”

The origin of the spindle, its behaviour towards the nucleus, the for- 
mation of the equatorial chromatin plate, the separation of the daughter- 
plates, the formation of the interzonal filaments, are phases in one 
continuous process.
