16 THE GROWTH AND PARTS OF PLANTS 
How the oak seedling escapes from the acorn. If you 
look for sprouted acorns, you will find them in different 
stages of growth. Some with the root just emerging 
will be found, and 
others with the “tail” 
an inch or more long. 
In these larger ones 
we can see that the 
part next the acorn 1s 
split into two parts. 
As it curves, this split 
often widens, so that 
we can see In between. 
In such cases a tiny 
bud may be seen lying 
close in the fork of 
the two parts. ‘This 
bud is the growing 
end of the stem, and 
we now see that the 
tiny plant backed out 
of the acorn. 
The root hairs. In Fig. 32. Still later stage of Fig. 29. 
this study of the seedlings grown under a glass, or in 
a box or vessel where there is no soil for the root to 
bury itself, you will see that the root soon becomes 
covered, a little distance back of the tip, with a dense
