The origin of the primary, or tap-root from the radicle of the embryo, the development of the root-system from it, and the relation of that system to the shoot in the normal Flowering Plant have been.

Its fixation in the soil by means of its root- hairs has also been noted. The details of its structure will now be examined, so that the facts mav serve as an introduction to the study of the functions which the root has to perform. The root is typically cylindrical, and accordingly its transverse 82.
