Sothat when conditions are favorable, such as temperature, healthy state of theplant, etc., this gliding of the particles or apparent streaming of the proto-plasm down one side of the cell, and back upon the other, continues inan uninterrupted rotation, or cyclosis. There are many nuclei in an internodeof nitella, and they move also. 21. Test for protoplasm.—If we treat the plant with a solution of iodinewe get the same reaction as in the case of spirogyra and mucor. The proto-plasm becomes yellowish brown. 22. Protoplasm in one of the higher plants.—We now wishto examine, and test for, protoplasm in one of the higher
