,AY THE PLAN OF THIS BOOK 



The acquisition of food, which is constructed by 

 plants inside their own tissues, as described in 

 Chapter 



The development of photosynthetic structures, 

 to which is devoted Chapter 



The release of energy, which supplies the power 

 indispensable for every kind of work, as shown 

 in Chapter 



The transformation of food into special sub- 

 stances needed for particular functions, as de- 

 scribed in Chapter 



[A suitable place for the chapter which is logi- 

 cally No. 2, as noted in column 2] 



The absorption of substances into the plant, 

 with development of absorptive structures; 

 hence Chapter 



The movement and removal of substances 

 through and out of plants, considered in 



Chapter 



[ The adjustment of individual parts to surroxmd- 

 ings, to which is devoted Chapter 



The development of protective adaptations 

 against hostile external conditions, discussed 

 in Chapter 



The formation and development of new indi- 

 viduals like those which produce them; hence 

 Chapter 



The development of sex-uniting adaptations, se- 

 curing the cooperation of two parents in pro- 

 duction of offspring; Chapter 



The formation of new parts and their increase 

 in size, to which is devoted Chapter 



The development of structures through cycles, 

 both ontogenetic and climatic, — Chapter .... 



The development of dispersive adaptations, se- 

 curing room for new individuals to grow, as 



described in Chapter 



to which is devoted Chapter
