THE AWAKENING OF THE SEED 



5. Corn, the germ is 

 located at [g) . 



6. Corn cut lengthwise, 

 showing caulicle (c) , plu- 

 mule {pD, 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 

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

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

 Peach, etc. When the seed- 

 case, or any part of it, remains 8. SunHower seed opened, showing 



attached to the seed the whole "r^-ieLt^lso"""'' ^'^ "^ 



Sunflower seed.
