These results may be interpreted as showing a) a high phosphate within a cell lowers the permeability of the cell, or b) exosmosis of phosphate is dominated principally by a constant rate of passage of this ion independent of the concentration gradient across the surface of the egg. This latter might mean that exosmosis depends on a metabolic process, or on saturation utilization of relatively few available attachment points within the chorion.

This latter might mean that exosmosis depends on a metabolic process, or on saturation utilization of relatively few available attachment points within the chorion. The latter hypo- thesis is consonant with the conclusion that phosphate penetrates into and is held in the chorion only (p. 231). The process of exosmosis can also be thought of as an ionic exchange, a concept closely related to the latter of these suggestions.
