LESSON VII 

 FRUITS RELATION TO THE PLANTS 



Secure, with the aid of the children, a collection of fruits 

 containing as many varieties as possible. With these samples 

 before the class, discuss the nature and uses of fruits. 



What is a fruit ? What is the difference between a fruit 

 and a vegetable? What is nearly always found in fruit 

 that is very important to the plant? What would happen 

 in a few years to the peach tree, for example, if all peach 

 trees should cease to bear fruit? What, then, is the most 

 important part of the fruit to the tree? 



Name all the fruits .that grow in the vicinity. Name 

 others that you are familiar with. Which grow on trees? 

 Which grow on vines? Which grow on bushes? Make a 

 list of each kind. What fruits grow wild? Which are 

 larger and better, wild fruits, or those that are cultivated? 



Once, most fruits and flowers grew wild and were small 

 and inferior. How did man improve them? What is the 

 difference in the plants of a neglected garden and those of 

 the same kind in a well-cared-for garden? By care and 

 cultivation for many years, man has greatly improved fruits.
