CHAPTER I 



WHAT PLANTS NEED (STUDY OF SEEDS) 



PLANTS, like ourselves, have their needs. If they 

 cannot satisfy their needs, they cannot grow. Some 

 plants have much better ways of satisfying their needs 

 than others. To watch them struggling to get what they 

 need, and to see in how many different ways they go 

 about it, is the most interesting part of plant study. 



This is what we shall try to learn about. Whenever 

 we look at a plant, we shall ask : What does it need? 



does it do to meet its needs ? How does every 5 

 part work to_help the whole? What enemies and 

 difficulties does the plant have to overcome? 



When we think over our own needs, we see that we 

 can live only a little while without food. Without 

 water we can hardly live more than a week; without 

 air only a few minutes. Then, too, we must keep warm, 

 and we need sunshine to keep us in the best health. 



Do plants have the same needs that we have ? Can 

 a plant grow without food or water or warmth ?
