THE PLANT AND THE SOIL. 1C) 



water of the soil, passes into the plant, is carried by the 

 circulation of the sap to all parts, and is used in helping to 

 build up the various parts of the plant. When matter gets into 

 the plant in this way that is not required, some of it may be- 

 come deposited in various parts of the plant, but much of it is 

 carried to the outside of the leaf and of the bark, and left there 

 as the water evaporates. In the case of some plants, more 

 mineral matter is taken up from the soil than the sap can hold 

 in solution, and some of the salts are found in a solid form in 

 the little sacs or cells of which the plant is made up. These 

 are often seen by a magnifying glass or microscope in the form 

 of crystals either in the cells or in the walls of the cells. 

 CONCLUSIONS : 



1. The water of the plant comes from the water of the soil, 

 hence the importance of rains. 



2. All of the mineral or ash material of the plant comes from 

 the soil, being carried into the plant in solution through the 

 roots. 



3. The mineral matter is carried to all parts of the plant in 

 the circulation of the sap. 



4. Some of the mineral matter that is not needed by the 

 plant is given off from the outside of the leaves and through the 

 bark. 



5. It is very important to have the mineral or ash material 

 required by the plant in as soluble a form as possible in the 

 soil, hence the importance of good cultivation and of proper 

 fertilizing or manuring.
