What is the function of root pressure in the movement of water in the xylem?
active transport of salts and mineral ions into the xylem; decreases water potential in xylem; water potential gradient established; water moves into xylem via osmosis
1 of 5
What is the function of cohesion-tension in the movement of water in the xylem?
solar energy source; evaporation of water; water potential gradient established across leaf; tension created in xylem; cohesion of water molecules maintain column due to H-bonding and adhesive xylem wall
