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 and phloem are the two types of vascular tissues found in plants. Xylem tissues transport water from the roots throughout the plant, while phloem transports food (suga â¦ rs) from photosysnthesis throughout the plant.Xylem: tubes that brings water and minerals from the roots into the leaf. There is a layer of living Phloem and there is a layer of living xylem. Both these layer produce dead tissue, the Phloem produces bark (dead protective outer layer), the â¦ xylem produces wood (dead supportive inner layer). Both the wood and the bark are dead.
