Detailed Solution

Xylem and phloem are called complex tissues because they are made of more than one type of cell that work together to transport materials in plants.

Plant vascular tissues are of two types — xylem for water transport and phloem for food transport. Each is called a complex tissue because it contains several specialized cell types performing different roles. Xylem includes tracheids, vessels, xylem fibers, and xylem parenchyma. Phloem includes sieve tubes, companion cells, phloem fibers, and phloem parenchyma. Together, they form the vascular bundle that connects roots, stems, and leaves. Their coordinated function ensures the movement of water, minerals, and food throughout the plant.
