A waxy barrier in the walls of endodermal cells in a plant root that prevents water and ions from entering the xylem without crossing one or more cell membranes.

The solution of inorganic nutrients conveyed in xylem tissue from a plant's roots to its shoots.

the upward push of phloem sap in a vascular plant, caused by the active pumping of mineral into the xylem by root cells.

The evaporative loss of water form a plant.

The binding together of like molecules, often by hydrogen bonds.

The attraction between different kinds of molecules.

transpiration-cohesion-tension mechanism

A transport mechanism that drives the upward movement of water in plans: transpiration exerts a pull that is relayed downward along a string of molecules held together by cohesion and helped upward by adhesion.

The solution of sugars, other nutrients, and hormones conveyed thoughout a plant via phloem tissue.

a plant organ in which sugar is being produced by either photosynthesis or the breakdown of starch. Mature leaves are the primary sugar sources of plants.

A plant organ that is a net consumer or storer of sugar. Growing roots, shoot tips, stems, and fruits are sugar sinks supplied by phloem.

pressure flow mechanism

The method by which phloem sap is transported through a plant from a sugar source, where sugars are produced, to a sugar sink, where sugars are used.
