The part of the vascular bundle responsible for transporting water and minerals is called the xylem. The xylem is a specialized tissue found in plants that helps in the conduction of water and minerals from the roots to the shoots.

The xylem consists of several types of cells, including tracheids and vessel elements. These cells are elongated, tube-like structures that are interconnected to form continuous pipelines within the plant. The xylem cells are dead at maturity and have thick cell walls that provide structural support.

Water and minerals are pulled up from the roots and transported through the xylem using a process known as transpiration. Transpiration occurs when water evaporates from the leaves through tiny pores called stomata. This evaporation creates a negative pressure, or suction, on the water column within the xylem, causing water to be pulled up from the roots. This process is aided by the cohesive and adhesive properties of water molecules, as well as the capillary action within the narrow xylem vessels.

Minerals, such as nitrogen, phosphorus, and potassium, are taken up by the roots from the soil. They are then transported through the root cells and into the xylem vessels, where they are carried upwards to the rest of the plant. The movement of minerals in the xylem occurs passively, driven by the flow of water.

Overall, the xylem plays a crucial role in the transport of water and minerals in plants. It allows for the distribution of essential nutrients and water to all parts of the plant, ensuring proper growth and functioning.
