38. xylem: The xylem is one of the types of tissue found in vascular systems. The xylem moves water and dissolved minerals upward from the roots to the higher parts of the plant. The xylem can be seen in the rings of a tree. The rings are remnants of xylem tissue, which means the xylem is the wood itself. The young oak tree in the picture is a good example of xylem, because it needs to take up water from the roots and carry it to the higher parts in order to grow.
