TWO monographs dealing with the properties of solutions have recently been issued by the, Carnegie Institution of Washington. The first, entitled “Osmotic Pressure of Aqueous Solutions,” is a report ...

In order to survive, organisms must control the pressure inside them, from the single-cell level to tissues and organs. Measuring these pressures in living cells and tissues in physiological ...

Hydraulic and osmotic properties of root systems of 2.5—8-months-old oak seedlings (Quercus robur and Q. petraea) were measured using the root pressure probe. Root pressures of excised roots ranged ...

1. Increasing the sorbitol concentration in a suspension of intact chloroplasts induced a fast, transient and not very specific efflux of metabolites from chloroplasts to the medium. Stroma proteins ...
