EXERCISE 38 



FIELD STUDY OF FOOD STORAGE 

 Materials. Various early spring plants in the field. 



Directions for work. In the early spring, when plants are 

 beginning growth, note which ones make a very rapid growth, 

 as shown by the formation of large and numerous leaves within 

 a few days or by very early flowering. Examine the under- 

 ground parts of these plants and note in how large a proportion 

 of cases you find evidence of food storage. 



Tabulate your observations as follows, giving the name of 

 the plant in each case (if known), the kind of food-storage organ 

 (as tuber, bulb, root, etc.), and the relative amount of storage.

 OF STORAGE 



REMARKS 



What do you find to be the relation between storage and
