Once in the xylem tissue, water moves easily over long distances in these open tubes (Figure 5). There are two kinds of conducting elements (i.e., transport tubes) found in the xylem: 1 ...

In a mature flowering plant or tree, most of the cells that make up the xylem are specialised cells called vessels.

As water travels through the xylem in the stem and leaf, it is being replaced by water taken up by the roots. Photosynthesis produces glucose in the green parts of plants, which are often leaves.
