Water and minerals move up and down the plant, supplying the stem and leaves through the help and action of gravity, osmosis, cohesion, and adhesion. This, however, occurs with the presence of vascular and ground tissues in the plant. Water moves into the root (through the root cap and root hair) in the soil (where water potential is high) through osmosis, and with the help of transpiration pull up the plant to other parts where water potential is low. Water is able to move up the plant against gravity with the help of cohesion force binding water molecules together and adhesion force which allows water molecules to bind to the wall of the xylem. And of course, gravitation force helps the downward movement of water. This is how water is being transported throughout the plant.
Also, in summary, the vascular tissues (xylem and phloem)- xylem functions in the conduction and transportation of water and mineral, while phloem stores the manufactured food in plants. The ground tissues (parenchyma, sclerenchyma, and collenchyma)-functions or aids in the manufacturing of food through photosynthesis.
