Answer:
The resultant pressure in the xylem attracts more water from roots[ Water flows from the root to a leaves through stem].
Explanation:
The cohesion-tension concept of movement of water throughout the xylem states that water pulls extra water from the xylem because of the cohesive nature of water because it evaporates through stomata. The resultant pressure in the xylem attracts more water from roots[ Water flows from the root to a leaves through stem].
The principle of cohesion-tension is an inter molecular interaction theory that explains the mechanism of water flowing upwards (against force of gravity) through plant xylem.
