12 Plant Physiology 



utilizes and advances these or any other sciences which 

 may assist in deducing the facts of plant life. Just as 

 chemistry may utilize the plant as an indicator of chemical 

 reaction or chemical fact, so physiology may use or develop 

 chemical facts in analyzing the phenomena of plant life. 



In general, a study of physiology must assume or in- 

 clude facts regarding the form and structure of plants; 

 that is, morphology and histology. The more elaborate 

 the morphology of an organism, as a rule, the more special- 

 ized and intricate are its reactions. These reactions are 

 those of its constituent units, and the cell is a convenient 

 and necessary unit of structure. The cell is likewise an im- 

 portant physiological unit, and as such requires special con- 

 sideration.
