this section, we examine two types of transport phenomena that, at first glance, may seem unrelated: the regulation of cell volume in both plant and animal cells, and the bulk flow of water (the movement of water containing dissolved solutes) across one or more layers of cells. In humans, for example, water moves from the blood filtrate that will form urine across a layer of epithelial cells lining the kidney tubules and into the blood, thus concentrating the urine. (If this did not happen, one would excrete several liters of urine a day!) In higher plants, water and minerals are absorbed by the roots and move up the plant through conducting tubes (the xylem); water is lost from the plant mainly by evaporation from the leaves. What these processes have in common is osmosis — the movement of water from a region of lower solute concentration to a region of higher solute concentration. We begin with a consideration of some basic facts about osmosis, and then show how they explain several physiological properties of animals and plants.
