All plants need water, minerals and food. There is a system present in plants called transport system to distribute these substances throughout the body.
Flowering plants have a very well developed system to transport these substances, this system is called vascular system. Vascular system contains two types of tissues, xylem and phloem.
Xylem distributes water and phloem distributes food throughout the plants body. Plants need water for photosynthesis, transpiration, transportation and for mechanical function. Minerals are also required by the plants as salts or as ions. Water is absorbed by the roots, [Fig. 2.1 (a)] for this, roots provide huge surface area, they contain cell sap of higher concentration than the surrounding water and root hair have thin walls. The vascular tissues are present in plant body from the tip of roots up to the leaves, xylem and phloem also joined end to end and form long tubes and phloem cells form long tubes for their functions.
