Answer
Xylem is responsible for bringing water up from the roots to the leaves of the plant. The upward transport of water depends on cohesion and adhesion to pull the water molecules against gravity. The concept of transpiration is also applied: as water leaves the plant from the leaves, another molecule is pulled upwards to take its place.
