WebTracheids are elongated cells that are found in the xylem of plants. They are responsible for transporting water and minerals from the roots to the rest of the plant. Vessel elements are also elongated cells that are found in the xylem of plants. The main functions of tracheid cells are to transport water and inorganic salts, and to provide structural support for trees. There are often pits on the cell walls of tracheids, which allows for water flow between cells. Tracheids are dead at functional maturity and do not have a protoplast.
