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.
Basically, xylem tranports water and phloem transports organic substances. Xylem is a tissue found in vascular plants that transorts water and dissolved mineral nutrients. It consists of hollow vessels that are formed from cells joined end to end in flowering plants. Xylem tissue in plants transports water and mineral salts from the roots up to the leaves. It also provides strength to the plants thanks to a woody substance called lig â¦ nin. Phloem in plants transports food (made in the leaves) to the rest of the plant.
