In addition, experiments were carried out in which the effect of external sodium concentration on potassium reaccumulation was studied. An examination of a large body of data indicates a close correlation between potassium content and calculated cell water in Ulra, while sodium content is 50 45 40 35V 25 20 POTASSIUM. 20 40 80 100 120 60 -hours- Fig. I. Influence of illumination and darkness on the potassium content of Ulva lactuca. most consistent on a dry weight basis. For these reasons the potassium and sodium are expressed as indicated although essentially the same results appear when the data for each ion are expressed on either basis. The variation in ion contents in these experiments cannot be a reflection of changing cell volume, since although the percentage dry weight varied between the limits of 25 and ^;^ there was no trend correlating with any variation in ion contents. Influence of Light and Dark. In these experiments two groups of algae were used, the one being maintained in the light throughout the experiment and the.
