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.
If you mean plants, that's a different category, but xylem and phloem are the vascular tissues of plants, found from roots through stem to leaves. In woody plants, this thin layer of tissue is found right under the bark.xygen diffuses directly from the air to corneal cells to keep the cornea transparent. There are fewer blood vessels in connective tissue and bone than in high metabolic areas such as muscle cells and organ cells, but blood vessels (vascular tissue) is found all over the body.
