Research Abstract	The cell mass of Scopelophila protonema appeared to be present in similar amounts under normal and copper- or zinc-enriched conditions, whereas the cell mass of Polypodium prothallium was reduced. The copper-treated cells showed the accumulation of copper during growth. The copper accumulated in Scopelophila protonema was bound to the cell wall pectin. Many glycoside hydrolase activities were detected in the soluble fractions from control and copper-treated cells. Uronic acids were found in similar amounts in cell walls of control and copper-treated cells, whereas the amount of some neutral sugars decreased.
