Even better, if the tissue fluids can be main- tained at a slightly higher pressure, then there will be a tendency for the needed water to enter the organism from the surrounding medium.

The degree of shading indicates the relative values of osmotic pressure. (Modi- fied from H. W. Smith, 1936). Most fresh-water and terrestrial plants can maintain an internal osmotic pressure ranging up to 2 atmospheres but they find saline habitats with a higher osmotic pressure physiologically too dry and uninhabitable. However, specially adapted plants, the halophytes,.
