PARE TL .00TS. AND TEMS 
ROOT: HATERS 
i AREFULLY pull up one of your bean plants 
and look at its root (Fig. 108). 
You see that the root grows downward from the 
lower part of the stem. 
This bean root looks not unlike a bunch 
of dirty threads, some quite thick, others 
very thin. If you look at these thread-like 
roots in a good light, perhaps you may be 
able to see growing from them a quantity of 
tiny hairs. 
Now, what is the use of such a root as this ? 
Surely some of you are ‘able to guess at 
the object of this root, and I will help the 
others to the answer. 
Give a firm though gentle tug to one of 
the larger plants,— one of those that are Het sar 
growing in the pot of earth. 
Does it come out easily in your fingers? 
Not at all. Unless you have been really rough, and 
used quite a good deal of strength, the little plant has 
kept its hold.
