Plant transport. No heart, no blood and no circulation, but plants do need a transport system to move food,water and minerals around. They use two different systems – xylem moves water and solutes from the roots to the leaves – phloem moves food substances from leaves to the rest of the plant

mechanism of water and minerals in a plant:
1)the vessels and tracheids of roots ,stems and leaves in xylem tissue are interconnected to form a continuous system of water conducting channels reaching all parts ofther plant.
2)the cells of roots in contact of the soil actively take up ions which creates a difference in the ion concentration between the root and soil.
3)thus there is steady movement of water into roots xylem from the soil creating a column of water that is pushed upwards.
