Water along with dissolved minerals is absorbed by the roots from soil. This absorption through the root hair cells occurs through osmosis. However, it cannot be transported to all other plant cells only through diffusion or osmosis. The plants have developed a well-defined system of conducting tubes for such transports and this system is called the vascular system.
It consists of two tissues:
Xylem tissue are majorly responsible to transport water and minerals from roots to all other plant cells.
In plants, vascular tissue xylem is responsible for transporting water and minerals in plants. Our phloem (tissue) transports products of photosynthesis from the leaves, where they are synthesized to other parts of the plant. Xylem and phloem are together known as vascular bundles.
In plants, transpiration creates a suction pressure and water is forced into the xylem cells of the roots of the plants. This movement of water from the root xylem to all the plant parts. After that plants possess the two transport systems which process to move water, minerals and food through their roots, stems, and leaves.
These processes are regularly working by using continuous tubes which are called xylem & phloem.
After that, the xylem cells in plants transport water and minerals from the soil to the leaves. These cells of the leaves, roots and stem are interconnected through medium to reach all parts of the plants. Therefore, there is a continuouly water movement into the xylem to other parts of the plants.
Transportation sequence takes place in the following process
