8. Seed—(1) Of trees (nuts)—beechnut, almond
(2) Of grasses (cereals)—wheat, corn, rice
(3) Of vines (legumes)—peas, beans, lentils.
In asking for examples of the different parts, there will be more interest and value if the questions correlate other subjects, for instance: For what fruit is Canada noted? What fruit does she import? Name a nut the squirrels gather.
Lesson II
COMPOSITION OF ANY PART OF A PLANT
From the foregoing, the pupils may infer that there are eight different foods to study. They should be led to see that in reality there is only one, as all parts of plants are, generally speaking, the same in structure. Referring to the animal body, they will know that a bone from the foot is of much the same structure as one from the face; that a piece of flesh from the leg is the same as a piece from any other part of the body. In the same way, if we study one part of a plant, it will be a type of all parts. In general the structure is as follows:
1. A framework, in cellular form, made of a substance called cellulose.
2. Material filling the cells:
(1) A juice in the cells of all parts of plants except seeds
(2) A solid in the cells of seeds.
To show the framework, some vegetable food having a white colour should be chosen, such as potato, parsnip, or apple.
