Chapter V 
STORAGE ROOMS 
V EGETABLES are really any part of the 
plant that is eaten, but the word usually 
means parts that are not sweet. Oranges, 
apples, and bananas are sweet and so are not 
called vegetables. Some fruits are vegetables, 
but all vegetables are not fruits. The difference 
will be seen later. Vegetables are good to eat 
because the plants have stored up food in them. 
Different plants choose different places to store 
food; vegetables, therefore, come from six parts 
of the plant. 
i. Tubers are thickened branches of an 
underground stem. The most common ex¬ 
ample is the white potato. It is good to eat 
because it is full of starch, which is one of the 
substances needed to give us heat and energy. 
2. Roots give us many of our vegetables: 
Potatoes 
are tubers
