Xylem cells are elongated cells with lignified secondary thickening of the cell walls. Xylem cells are specialised for conduction of water, and first appeared in plants during their transition to land in the Silurian period more than 425 million years ago (see Cooksonia). The possession of xylem defines the vascular plants or Tracheophytes.
Xylem. Xylem is tough, woody tissue that transports water and minerals from the roots of the plant to the stem and leaves. Flowering plants develop xylem vessels, cylindrical cells stacked end-to-end.When the plant matures, the ends of the cells disintegrate and the cell contents die, leaving long non-living tubes.lants turn sunlight into sugar in their leaves, while their roots extract water and minerals from the soil. But these valuable products must be transported throughout the plant in order for it to survive.
