It is more important,however, if facilities are at hand, to set the pupil to the study ofthe behavior of seeds and plautlets in germination. An interestingseries of studies can be made from a comparison of the form ofthe cotyledons with that of the first true leaves, and of the grada-tion from the character of the first leaves to those which arecharacteristic of the mature plant. Are there differences in coty-ledons and first leaves between the different horticultural varietiesof the same plant, as between the different kinds of tomatoes and 336 LASSONii iriTU PLANTS red peppers ?
