Osmotic pressure is the force water exerts on the semi-permeable membrane (plasma membrane) surrounding the cell. Water moves across the plasma membrane in response to an unequal distribution of ...

How do guard cells change their volume to control this opening and closing? They do so by changing the osmotic pressure of their vacuoles, which then either take up or lose water, and consequently ...

While chemical signals such as morphogens have been known for a long time, fluid transport has recently emerged as another potential way to globally organize cell behavior during morphogenesis (Navis ...

It works primarily by an osmotic effect but also has other effects ... Volume expansion improves blood pressure and cerebral perfusion pressure. Improved perfusion yields better oxygenation ...
