The problems associated with the movement of water and solutes throughout the plant body have intrigued students of plants since Malpighi's conclusions in 1675 and 1679 that nutrient sap flows upward and downward in stems through vessels in both wood and bark. Steven Hale's ingenious experiments on the movement of water in plants in 1726 and Hartig's observations of sieve-tube exudation in the mid-19th century set the stage for continued intensive studies on long-range transport in plants.

This book provides a broad overview of solute transport in plants. It first determines what solutes are present in plants and what roles they play. The physical bases of ion and water movement are considered. The volume then discusses the ways in which solutes are moved across individual membranes, within and between cells, and around the plant. Having dealt with the role of plant solutes in 'normal' conditions, the volume proceeds to examine how the use of solutes has been adapted to more extreme environments such as hot, dry deserts, freezing mountains and saline marshes.
Xylem transport is unidirectional. phloem transport is bidirectional. but transport in plants is multidirectional. simple diffusion is along concentration gradient. facilitated diffusion is against concentration gradient. gaseous movement occurs by diffusion. Facilitated diffusion; soluble in lipids lipophilic can pass through simple diffusion. soluble in water hydrophilic(liphophobic)insoiuble in lipids carried protein on this inside surface-facilitated diffusion.

Transportation in Plants is the vital process which helps in transporting water and solutes from the roots, stem, leaves and rest of the plant. The following figure illustrates the active transport in the cell: First ATP denotes a phosphate to a particular gateway molecule than it pumps the desired molecule across the membrane.
