Water enters the root of plants by osmosis. The difference in osmotic pressure between the plant root cells and the soil creates osmotic pressure of water in the root hair cells.
Osmosis is the movement of solvent ( in this case, water ) particles from a region of less concentration of solution to a region of more concentrated solution through a semipermeable membrane. Osmotic pressure is the force needed to prevent water from going back down the concentration gradient.
In the process of absorption of water by plants through the roots, the root cell membrane acts as the semipermeable membrane and the root hair cells act as regions of higher concentration due to accumulation of absorbed minerals from the soil. The soil always has a lower concentration than the root hairs, therefore the osmotic pressure formed in the root cells cause movement of water molecules into the roots and into the xylem vessels of the plant.
