THE FULL-GROWN PLANT AND ITS PARTS 
I. THE PLANT 
The plant has different parts. The seedling has roots, 
stem, and leaves. The full-grown plant has the same 
parts. But the roots, of course, are larger, longer, and 
much more branched. There are many more leaves 
also, and the stem is often very much branched. Are 
there any other parts? There are the flowers, you say, 
and the fruit, and some plants have thorns, spines, 
hairs, and tendrils. Yes, but many plants have just 
the root, stem, leaves, flowers, and fruit. And how 
different they are in different plants! Did you ever 
notice that the form of the stem, and the shape and 
arrangement of the leaves and flowers mark the differ- 
ent kinds of plants so that you can tell them apart? 
The form of the entire plant we call its appearance or 
habit. The seeds of each kind of plant make new plants 
of the same kind and shape. 
Tall, erect plants. The sunflower is tall and slender. 
At first there is a simple, straight, tall, shaft-like stem, and 
large, Spreading leaves pointing in different directions.
