THE AWAKENING OF THE SEED 



5. Corn, the germ is 

 located at (g). 



6. Corn cut lengthwise, 

 showing cauliele(c), plu- 

 mule (pi), seed-leaf (0 

 and endosperm (e). 



which is thin, transparent and fits snugly. If we 

 cut through the grain, as shown in Fig. 6, we see 



the germ, consisting 



of a single seed- 

 leaf (I) with cau- 



licle, plumule and a 



large mass of en- 



dosperm, which in 



Sugar Corn is clear 



and sugary, while 



in ordinary Corn 

 it is hard and yellow on the 

 outside, but floury toward the center. 



In some plants the seed is covered only by the seed- 

 coat (the skin of the bean is such 

 a seed -coat), while in others it is 

 covered by the seed -coat plus a 

 part of the seed -case (the seed- 

 case corresponds to the pod of the 

 bean) ; the seed- case may be con- 

 solidated with the seed -coat, 

 as in the Corn, or be separate 

 from it, as in the Sunflower 

 (Pigs. 7 and 8), Peanut (Figs. 

 9 and 10), Walnut (Fig. 24), 

 Peach, etc. When the seed- 

 case, Or any part Of it, remains 8. Sunflower seed opened, showing 



, , caulicle (c). plumule (pi) and 



attached to the seed the whole seed leaves w).
