The structure that transports water and nutrients from the roots to the rest of the plant is called the xylem.

Here's how it works:

* Xylem is a type of vascular tissue that forms a network of tubes throughout the plant.

* Water and dissolved minerals are absorbed by the roots and enter the xylem.

* The xylem vessels are made of dead cells that have been joined end to end, forming a continuous, hollow tube.

* Capillary action and transpiration (the evaporation of water from the leaves) create a pressure gradient that pulls water up the xylem from the roots.

Think of the xylem as a series of straws that deliver water and nutrients from the roots to the leaves and other parts of the plant.
