Why should that be true ? Which end bursts out 
first in the bean? In the pea? In the acorn? 
Beechnut ? 
7. What provisions the plant has for developing. 
Review the store of nourishment in each of the 
seeds planted, distinguishingbetween exalbuminous 
and albuminous seeds. See discussion of this in a 
previous chapter. What are the two halves of the 
bean used for? Of the pea? The acorn? Why 
do not the acorn and pea rise above the surface of 
the ground and form the seed leaves as the bean 
does? How about pumpkin seed, squash, water¬ 
melon and corn? Wheat? Where is the food 
supply in each case ? What does the young plant 
do for food after the store of nourishment is all 
used up ? 
Have pupils point out the parts of the young 
plantlet even in the dry seed before it is planted, 
and then notice day by day the development of seed 
leaves, plumule, caulicle and roots, and finally the 
wasting away of the store house of nourishment. 
8. Study roots, stems, in relation to flowers as 
organs for taking in, etc. See lessons already given 
in preceding grades. 
9. Study forms of roots, leaves and stems. See 
third and fourth grade work. 
10. Examine and compare leaves, seeds, 
prickles, etc. See work for preceding grades.
