Leaves, stems, roots, and flowers are all made up of various tissues.

Xylem and Phloem are the vascular tissues of plants. Xylem is the plant tissue that form the vessels that transport water and mineral salts absorbed from the soil to plant cells. Phloem is the plant tissue that forms the vessels that transport dissolved sugar from the leaves (where it is produced via photosynthesis) to other plant cells.
