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.
Phloem is a type of tissue found in plants. Along with xylem, phloem makes up the transport system within plants. Phloem and xylem are completely separate within the transport system. Both tissues are found throughout plants and each carries different substances to and from different parts of the plant.hloem, and xylem, tissue is arranged so that cells join end to end to form long tubes throughout the plant. The cells that make up the transport system have been modified to allow easier transport through the plant. In xylem tissue, the cells are dead.
