"Now think of our old lessons on the
grain plants, and you will be able to tell me what kind of leaves they all have, corn as well as the rest.""These all have parallel-veined leaves," said Norah. "The veins run throughthe leaves, side by side, from base to tip.""Remember, then," said Fred,
"that all plants bear parallel-veined leaves that come from seeds with a single seed-leaf.""Does the little seedling get its food from this one seed-leaf, Fred?""No, Norah," said Fred. "In all these seeds thefood store is laid up in the grain, which surrounds the germ, and not in the seed-leaf. The seed-leaf itself is not thick and solid like those of the bean."SUMMARY
The germ of the grains has only one seed-leaf. The food- store to feed the growing germ is laid up in the grain itself, and not in the seed-leaf. All plants that grow from such seeds have parallel-veined leaves.
