From between these starts a tiny bud, that soon unfolds into a fresh leaf, which is carried upward by a new piece of stem.
On the tip of this new piece of stem grows another bud, which also enlarges into a leaf, and in the same way as before is borne upward (Fig. [122]).

In this fashion the plant keeps growing bigger and bigger. Soon branches start from the sides of the stem, and later flowers and fruits.
So we see that it is the stem which bears all the other parts of the plant.
Most people think that the plant springs from the root; but you children know better. With your own eyes, here in the schoolroom, you have seen that instead of the stem growing from the root, the root grows from the stem.
