Pond Life 
( Continued) 
As may be supposed, many plants 
which live in ponds have special ways of 
their own suited to a life in the water. 
One plant is brought up to the surface 
at the proper time by bladders attached 
to the leaves. As soon as their work is 
done the bladders collapse and the whole 
plant goes to the bottom. Other plants 
have their below-water leaves long and 
thin, so as not to hold or obstruct the 
water and make a drag, while their upper 
leaves are big and flat, and float on the 
top to support the flowers.
