The part of a plant where water travels is called the xylem.

Here's how it works:

* Roots: The roots absorb water from the soil.

* Xylem: This is a network of tubes that runs throughout the plant. Water is transported upwards through the xylem, from the roots to the leaves and other parts of the plant.

* Leaves: The leaves use the water for photosynthesis, the process that creates food for the plant.

So, the xylem is like the plant's plumbing system, carrying water throughout its body.
