摘要：

Osmotic volume change was measured for drops of protoplasm isolated from internodal cells of Chara australis in inorganic salt solutions of various osmolalities. A drop was found to maintain a definite volume in medium of a definite concentration in such a way that VAN'T HOFF'S law practically holds. This indicates (1) that the surface membrane surrounding the isolated drop is semipermeable, and (2) that practically all the space of the protoplasmic drop is osmotically active. © 1969 Oxford University Press.
