HOW PLANTS GROW FROM THE SEED.

leaves supplying abundant materials for the growth. A cherry-seed is just like an 

 almond, only on a smaller scale. Fig. 38 is the embi'yo of a Cherry, with the 

 very thick seed-leaves a little separated. Fig. 39 is the same developed into a 

 young plantlet. Fed by the abundant nourishment in the seed-leaves, it slioots up 

 its stem and unfolds three or four leaves before the Maple (Fig. 28, 29) or the 

 Morning-GIory (Fig. 20-22) 

 would have made any. It is 

 the same in the Chestnut and 

 the Beech. In these, as in the 

 Cherry and the Bean, the thick 

 seed-leaves, which make the 

 whole kernel, come up, turn 

 green, and become thinner as 

 they give up their load of 

 noui'ishment to the jrrowina; 

 parts ; they evidently try to 

 become useful green leaves ; 

 but having been used for hold- 

 ing nourishment, they remain 

 too thick and clumsy for foli- 

 age, and they soon die or fall 

 off. But in

Acorn, and llie Pea, the seed- 

 leaves are so very thick, and 

 so heavily loaded, that they 

 never undertake to serve any 

 otlier purpose than that of 

 feeding the other parts as they 

 grow. So they remain in the
