While the movement of water through xylem tissue is relatively ... especially sugars, in the phloem of source tissues such as leaves would draw water into those vessels from surrounding cells ...

The phloem transports sugars from leaves to ... The major structures for water transport in xylem are vessels in angiosperms (hardwoods) and tracheids in gymnosperms (conifers).

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.
