(After Sachs, from Strasburger.) covering the several particles, the root can by its hairs tap those films, however thin they may be in a dry soil. It is important further to realise how numerous these root-hairs are. It has been estimated that over two hundred of them may be borne on one square millimetre of surface of the root of a Pea, while in other plants, for instance the Maize, the number may be still higher. The effect of this is greatly to increase the possible absorptive surface of 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 Bower, F.
