The cells in vascular tissue are typically long and slender. Since the xylem and phloem function in the conduction of water, minerals, and nutrients throughout the plant, it is not surprising that their form should be similar to pipes.
Plants have two types of transport tissues, xylem and phloem. Xylem is a plant vascular tissue that conducts water and dissolved minerals from roots to all other parts of the plant. Xylem is derived from a greek word xylon which literally means wood. Xylem is the primary element that forms the wood of the plants.
