What are the differences between the transport of materials in xylem and phloem?

Explanation

(i) Xylem tissue transports water and dissolved and dissolved minerals in plants whereas phloem tissue transports the food (made by photosynthesis) to all the parts of plant.
(ii) Xylem tissue carries the water and dissolved minerals only upwards from the roots of the plants but the movement of food from the leaves the leaves through phloem can be upwards as well downwards depending on the requirements of the plant.
(iii) The upward movement of water and dissolved minerals in xylem tissue is caused by a suction force produced by the continuous evaporation of water (or transpiration) from the cells of leaves of the plant which pulls up water from the roots. On the other hand, the food made in leaves is transported through phloem tissue by utilising energy from ATP.
