S ummary The volume in carrot tissue apparently not penetrated, AOV, by a plasmolysing solution of cane sugar, potassium nitrate, potassium chloride or calcium chloride is a linear function of the reciprocal of the osmotic pressure of the solution over the range of the concentration used. This AOV, which includes the solids in the cell walls, is practically independent of the nature of the electrolytes but appears to be greater for cane sugar. There is no clear evidence for any active transport of water into the vacuoles of the cells.
