Membranes and Transport Systems in Plants: An Overview - JSTOR
Such selective transport re-quires an input of metabolic energy, and in plants this occurs via the production of proton electrochemical gradients across the membrane by substrate- (ex. ATP, PPi) driven proton pumps. Selective solute transport is then mediated by mem-brane-associated secondary transport systems which utilize

Transport Systems TRANSPORT IN PLANTS Plants have a system that transports water and dissolved minerals as well as food manufactured in the leaves. Plants have two vessels that transport substances. The xylem carries water and dissolved minerals. These are hollow vessels that have been lignified so that they do not collapse.

- Light: Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata. Light also speeds up transpiration by warming the leaf. - Temperature: Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises. At 30°C, a leaf may

Plants have a system of simple tubes, called xylem, which transport water and mineral salts from the roots to the leaves. Another set of tubes, called phloem sieve tubes, transport nutri-ents such as sucrose and amino acids from the leaves to the rest of the plant. In this unit you will look at how water and mineral salts enter
