225. The Fruit of the Bean and 

 Corn. — In science the term fruit 

 includes much more than the 

 meaning we usually give it when 

 we refer to apples, oranges, or 

 berries. By fruit the botanist 

 means the ripened ovary of a 

 plant and its contents. The 

 first step in the production of 

 fruit is the pollination of the 

 stigma of a flower. Next comes 

 the fertilization of the egg cell 

 in the ovule. Finally the ovule develops into a seed, and 

 at the same time, the ovary grows to protect and to pro- 

 vide nourishment for the 

 seed until it is mature. 



In the bean plant the 

 pod begins to develop 

 from the pistil as soon as 

 fertilization has taken
