What makes xylem and phloem complex tissues?

They are made of more than one type of cells that coordinate to perform a common function.

What is the main function of xylem in plants?

Transporting water and minerals vertically from soil to aerial parts of the plant.

What is the primary role of phloem in plants?

Transporting food from leaves to other parts of the plant and from storage parts to other parts.
