 Tap-Moots and Fibrous Hoots. 



THERE are two classes of roots, called tap-roots 

 and fibrous roots, which differ from each other in the 

 way shown in Figs. 234 and 235. 



FIG. 234. FIG. 235. 



Tap-root. Fibrous Root. 



Fig. 234 represents a TAP-BOOT, which is seen to 

 be simply a continuation of the stem downward. 



In Fig. 235 the stem is not continued downward 

 as a tap-root, but sends off rootlets or fibres at the 

 outset. It is hence called a FI'BKOUS ROOT.
