What is the function of the xylem in plants?

The function of the xylem in plants is primarily to transport water and nutrients from the roots to the rest of the plant. The xylem is a specialized type of tissue that consists of vessels and tracheids, which facilitate the upward movement of water due to capillary action, evaporation from leaves (transpiration), and root pressure. This transport system is vital for nourishing the plant, as water is essential for photosynthesis and various metabolic processes. Additionally, xylem helps in the transport of dissolved minerals absorbed by the roots, which are crucial for plant growth and development.

The xylem also contributes to the structural integrity of plants, but its primary role is in fluid transport, distinguishing it from other tissues that may serve different functions such as energy storage, support, or reproduction.
