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.
These vessel elements make up the xylem-and are many elongated cells laid end to end, and normal plant cells have walls strengthened by lignin, a hard strong substance that is impermeable to water, and is designed to provide structure and strength to the plant.rom the root hair cells, water again moves down a concentration gradient toward the xylem, and can take one of three paths-apoplast and symplast and vacuolar. The apoplast pathway is where water takes a route going from cell wall to cell wall, not entering the cytoplasm at any point.
