Fig. 3.) The result of these changes is that either directly 

 or indirectly the nucleus splits into two, and the protoplasm 

 divides and arranges itself around the new nuclei ; these 

 daughter cells soon grow to the size of the parent cell, and 

 division of these and consequent multiplication may proceed 

 with great rapidity. 



To sum up : The cell assimilates, is continually building 

 itself up and replenishing its store of energy, is as continually 

 breaking down into simpler products with a setting .free of 

 energy ; it grows ; it moves ; it reproduces itself in other 

 words, it is alive and is the basis of all life.
