Plants have developed vascular systems to transport nutrients and water throughout their large bodies. The xylem transports water and minerals up from the roots through dead conductive cells, while the phloem transports organic nutrients down from the leaves through living cells. Transpiration is the evaporation of water from leaves, and creates a transpirational pull that drives water absorption by roots and transport through xylem vessels up the stem using capillarity and osmosis.

1. Transport in Plants

2. Body is too large.Diffusion from the external environment is not an optionWhy do large organisms need a transport system?

4. Most plants have developed complex vascular systems that move nutrients and water throughout the plant body through "tubes" of conductive cells. The vascular tissues of these plants are called xylem and phloem. Transport Systems

5. The xylem of vascular plants consists of dead cells placed end to end that form tunnels through which water and minerals move upward from the roots (where they are taken in) to the rest of the plant.Xylem

6. Phloem, which is made up of living cells, carries the products of photosynthesis (organic nutrients) from the leaves to the other parts. Phloem

7. Absorption of Water

9. TranspirationTranspiration is the evaporation of water into the atmosphere from the leaves and stems of plants.
