On the well-drained roots you will find hundreds of tiny feeding hairs, while on the badly-drained roots these feeding hairs will be absent or few in number.

No wonder the wheat in a wet patch of ground has a starved look ! 5. How the hairs on the root take in food. The hairs on the root are, as we saw, delicate cells that suck in water. Now these hairs will not grow in soil that is kept constantly wet. Hence the poor growth of wheat in wet, badly- drained soil. In warm, loose, moist soil, on the other hand, the number of roots and rootlets and root-hairs is astonishing. Every particle of soil seems to be searched. A large mar- row, growing in such soil, was found to have roots which, if put end to end, would have measured over 15 miles! 6. Plants that thrive in wet ground. But here you ask me : " Why, then, do some plants thrive in sodden ground, and even in water ? " Well, you must never forget that Nature has no vacant plots in her great Earth-garden. Every patch of ground is turned to account to support hfe of some kind. And so plants have been gradually trained for wet soils and for ponds. You may see on the margin of a pond a grass, or reed, or tree that likes to have its roots always in sodden soil. Further in, you find a plant that likes to have its feet in water and its stem in the air; and, still further in, you see a plant that likes to have both stem and root in Outer skin of root â with root-hairs (much enlarged), showing that the hairs are simply extensions of 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 Gillies, William.
