Water is pulled up through xylem to the leaves of the plants by the process of transpiration. Following steps take place during this process:
It is known as the transpiration stream
The water enter the roots from the soil by the osmosis
After that the water either enter the cell wall of the xylem or goes to the cortex cell
Next, as the water from the leaves is being evaporated ,a negative pressure is created at this end(leaf end of the xylem) ,a positive pressure at the other end of the xylem(root end)
This change in the potential gradient causes the water to move up the xylem to the leaf through diffusion .
