Trace. 
1) If we make a vertical cut through the surface of the root, we can observe 
under the microscope in many cells globular masses consisting of active albumen 
which may have been separated from the dissolved albumen by mechanical action 
but after treatment with coffein the quantity is considerably increased. There is 
present much tannin in the hot water extracts of the stem but not in those of the root.
