osmosis \os*mo"sis\ ([o^]z*m[=o]"s[i^]s), n. [NL., fr. Gr. 'wsmo`s, equiv. to 'w^sis impulse, fr. 'wqei^n to push.] (Chemical Physics)
-
The tendency in fluids to mix, or become equably diffused, when in contact. It was first observed between fluids of differing densities, and as taking place through a membrane or an intervening porous structure. An older term for the phenomenon was Osmose.
Note: The more rapid flow from the thinner to the thicker fluid was then called endosmosis (formerly endosmose), and the opposite, slower current, exosmosis (formerly exosmose). Both are, however, results of the same force. Osmosis may be regarded as a form of molecular attraction, allied to that of adhesion. See also osmotic pressure.
The action produced by this tendency.

As I was doubtful whether this was due to the cells on the upper surface of the lobes, or to the sensitive filaments, being acted on by exosmose, one leaf was first tried by pouring a little of the same solution in the furrow between the lobes over the midrib, which is the chief seat of movement.
I presume, is due to their having been strongly affected through exosmose, so that they continue for some time to transmit a motor impulse to the upper surface of the leaf.

When drops of syrup are placed on the leaves of plants with their roots still in damp earth, no inflection ensues, for the roots, no doubt, pump up water as quickly as it is lost by exosmose.
