Publisher's Synopsis
Excerpt from The Water-Balance of Succulent Plants
The activities of the seed-plant make necessary a movement of solu tions from the surface intakes of roots or other absorbing organs in con tact with the medium or substratum to various tissues, the residue of liquid and content finally reaching the excretory or transpiratory mem branes of the leaves, stems, or other aerial members. This water-service involves a supply of available moisture in the substratum or medium, absorbing organs, whose tissues sustain a higher osmotic activity than the substratum, conducting tracts of adequate capacity, and transpiratory organs, which in response to the evaporating action of the air throw ofi the water of the solutions entering the roots, in the form of vapor, at a rate variously modified by the purely physiological activity of the protoplasts. The individual and contributory action of all of these factors is greatly influenced by many internal and external conditions, physiologic, morpho genic, and physical. The relation of the plant to the moisture-supply and to the evaporating capacity of the air constitutes a limiting factor of great importance in determining distribution and habitat selection.
