Use of Fruit. â The fruit holds and protects the seeds until the time comes when tlie>' are able to germinate and produce new plants Uke the original plant from which they grew. Then, as we ha^'0 seen, it helps to scatter them far and wide. The Bean Seed. â ^^'e have already been able to identify in the pod of the bean the style, stigma, and ovary of the flower. The opened pod discloses the seeds lying along one edge of the pod, each attached by a little stalk to the inner wall of the ovary. If we pull a single bean from its attachment, we find that the stalk l('a\'es a scar on the coat of the bean; this scar is called the hihnn. The tiny hole near the hilum is called the micropyle. Turn back to the Figure (p. 37) showing the ovule in the ovary. Find there the little hole through which the jiollen tulx- ivachcd the embryo sac. This hole is called the micropyle, and is identical HUNT. ES. BIO.â5 65.
