In highly organized plants, the transport system consists of:
- Xylem: Transports water and minerals from roots to leaves.
- Components: Tracheids, vessel elements, xylem fibers, and xylem parenchyma.
- Phloem: Transports the products of photosynthesis (mainly sugars) from leaves to other parts of the plant.
- Components: Sieve tube elements, companion cells, phloem fibers, and phloem parenchyma.
