Seeds and their Germination ly 



formed toward the tip. They make their way in between the 

 fine particles of soil in search of water. 



Fasten some seeds, which have germinated until the roots 

 are about an inch long, to strips of wood. Place them in an 

 inverted flower-pot, in which the water stands to a height of 

 two inches. Let the roots in one dip into the water; place 

 the second lot higher, taking care that they are some distance 

 above the water. After they have grown an inch or two, note 

 the absence of root hairs in one lot of roots. If there is an 

 abundant supply of water, there will be no need to provide 

 special growths to obtain it.
