The root takes in water containing food : Can it use this 

 food material directly in making root-growth? Why? 



Why is starch stored in seeds and tubers? 



Is starch stored in twigs in the fall ? 



Are the flowers of peaches, and other early-blooming j^lants. 

 fed from food taken in at the root at the time, or from materials 

 stored in the twig ? (Think how the potatoes sprout in the bin.) 



Will mulching the roots of a peach tree with straw \\lien the 

 ground is frozen delay the blooming in spring ? 



Soil water holds very little food for plants: the roots must 

 take in enormous quantities of water : What becomes of some 

 of this water ? 



Is the water which evaporates from the soil of any direct use 

 to the plant ? 



The plant needs water, — it sweats it out : How shall we man- 

 age so that the plant can have all the water it needs?
