After that joining together, the seed begins to develop around the embryo, and the fruit begins to develop around the seeds. A supply of food is deposited around the embryo ready to be used up by it as it grows. Even while it re- mains in the seed, and even while the seeds remain in the fruit, and even while the fruit remains in the flower, the embryo grows. After it has reached a certain size, it may stop growing for a long time. You know that seeds may be kept a long time and still be good for sprouting. But when the seed does begin to sprout, there is the little plant within it, quite large enough to be seen with the naked eye, and ready to develop rapidly the parts which will enable it to make its own food and begin an independent exist- ence. (See Figure 21.) Open a seed to see. A bean or a pea- nut kernel will do. Within the protecting coats you find an oval body which separates easily length- wise into halves. These halves are parts of the embryo Fig. 21.—Diagram of a seed of vio- let.
