The part of the plant that contains vascular tissue through which water and nutrients travel is the xylem.

Here's a breakdown:

* Xylem: This is the specialized tissue that transports water and dissolved minerals upwards from the roots to the rest of the plant. It's made of dead cells with thick cell walls that form hollow tubes.

* Phloem: This is another type of vascular tissue that transports sugars (produced during photosynthesis) from the leaves to other parts of the plant.

So, while both xylem and phloem are vascular tissues, it's the xylem that's responsible for the transportation of water and nutrients.
