Statement 1: |
In angiosperms, the conduction of water is more efficient because their xylem has vessels. |
|
Statement 2: |
Conduction of water by vessels elements is an active process with energy supplied by xylem parenchyma rich in mitochondria. |

(c) In angiosperms, the two principle types of conducing elements in the xylem are tracheids and vessel elements. A linked row of vessel elements forms a vessel. Conduction of water through these elements does not use active energy. Thus, it is a passive process. In addition to conduction cells, xylem likewise includes fibres and parenchyma cells. |
