grows upward you will see a little bud made up of 

 several tiny leaves. The two halves of the bean are 

 the first leaves of the embryo and are so large because 

 the reserve food supply is stored in them. These 

 seed leaves are called cotyledons. 



A grain of corn or wheat has one small cotyledon, 

 and the food supply is not stored within the germ 



itself, but lies outside. You 

 can easily remove the small 

 germ of a grain of corn from 

 the harder part of the seed 

 which is the reserve food 

 supply. 



Good seeds. Good crops 

 can be grown only from good 

 seeds. As a rule, plump, 

 heavy grains are good seed. 

 The seeds of our crops keep 



their vitality for only a very few years, most of them 

 only two years ; and it is very important that the seed 

 is not too old. Seeds keep best in a dry, airy, cool 

 place. 



Germination. When seeds are placed in the ground, 

 the warmth, moisture, and air of the soil cause them to

 supply stored in the seed, but, after a short time, the 

 roots take in food material from the soil.
