The littlestem which is pushing its way out is also splitting. Between the two halves of the stem we now getsight of something new. It is the most wonder-fuLof all. There are-some little leaves unfolding.In a few days more they have opened. They arevery delicate and tender, but just like the leavesof the horse-chestnut tree from which the nutcame. The end of the little stem has reached theground and is pushing down into it. This stem isto be the root of the little plant. Branching rootletsare already starting from it. But how can the plant grow before it has anyroots? It is being fed from the white materialwithin the nut. This is mostly starch. It is justwhat the little plant needs before it can shift foritself. The two halves of the nut which we havediscovered are the seed leaves. After a time theplant will use up all of the food stored in them. 128 HOME GEOGRAPHY.. They will be of no more use andwill shrivel and die. By this time the little roothas gone far down into theground. The branching root-lets are growing. The leavesare now large enough to help.There are more of them andthey are reaching up into the air.The roots take the food fromthe soil. This food passes upthrough the stem to the leaves.The sun shines upon the leavesand changes the food in such away that the plant can use it. A tiny plant lay readyformed in the seed or nut. Itwas the germ or embryo.Warmth and moisture were allthat was needed to wake it intolife. It will grow year afteryear and at last become a tree.Then you will find upon it in thespring long clusters of flowers, and in the fall the pretty red-brown nuts like the one youhave studied.
