There are two kinds of conducting elements (i.e., transport tubes) found in the xylem: 1) tracheids and 2) vessels (Figure 6). Tracheids are smaller than vessels in both diameter and length ...

the most commonly used parameter to study xylem water transport), mean vessel diameter (MVD) and mean hydraulic diameter with increasing root topological orders. Furthermore, fine root vessel and ...

Xylem Xylem vessels Transport water and dissolved minerals from the roots, up the plant. Growing points Meristem Produce new cells by mitosis.

The sucrose is transported around the plant in phloem vessels. It needs to be able to reach all cells in the plant so that the sucrose can be converted back into glucose for respiration.
