The elongation of the basal portion of the hypocotyl frees the root from the seed and the growth of the upper region of the hypocotyl pushes up into the air the cotyledons and growing point or epicotyl. The formation of the stem is sometimes due to the elongation of the epicotyl alone, the cotyledons frequently containing the storage foods for the nourishment of the young plant and remaining buried in the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Curtis, Carlton Clarence, 1864-1945.
