These functions are: * For mechanical support * For conduction of water * For conduction and storage of manufactured food * For continuous growth of the stem in thickness These functions are centered at the fibro vascular system that is composed of two major tissues‚ the xylem and the phloem.

The phloem and the xylem are complex tissues that perform the transportation of food and water in a plant‚ They are both vascular tissues of the plant that together form vascular bundles‚ they work together as a unit to make the transportation of food‚ nutrients‚ minerals and water effective. The xylem is a tubular shape that has no cross walls which allows a continuous column of water and minerals a more rapid transport within the xylem‚ there are two types protoxylem first formed xylem and metaxylem

and tracheids are used for conduction of water and numeral salts from roots to the leaves and other parts of the plant. Xylem parenchyma assists them in their task and also serves for food storage and wood fibres give proper rigidity to the xylem. Except wood parenchyma all other xylem elements are thick walled‚ lignified and dead and hence they also give mechanical strength to the plant body. The first formed xylem or Protoxylem consists of annular‚ spiral and scalariform vessels. It lies towards
