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, distinguishing between 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.
