The two conducting tissues in highly organised plants are the xylem and phloemxylem and collenchyma. Tracheids, vessels, xylem parenchyma, and xylem fibres make up the xylemphloem. It is a type of lignified tissue. The root pressuretranspiration pull is caused by the evaporation of water from the leaves. This causes water to move upward from the roots through the xylem. It only shows unidirectional flowmulti-directional flow.

 

Xylem transports waterfood from the roots to various parts of the plant.  The phloem transports nutrients and food from the leaves to other parts of the plant. Sieve tubes, companion cells, phloem parenchyma, and phloem fibres make up the phloem. A phloem is a tissue that is not lignifiedlignified. They transport nutrients through the transportation process. Using hydrostatic pressure, it shows multi-directional flow.
