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.
