Why and how does water enter continuously into the root xylem?

(N/A) The cells of the root are in close contact with the soil and actively take up mineral ions from the soil.
This accumulation of ions increases the solute concentration inside the root cells,which in turn increases the osmotic pressure.
Due to this difference in osmotic pressure,water moves from the soil into the root cells by osmosis.
This process creates a steady movement of water,which then enters the root xylem and is transported upwards.
