Expert Answer:

Vascular bundles play a vital  role in transport and absorption of water. Xylem transports water from the roots to the all the parts of plant whereas phloem transports the  food which is prepared in the leaves by the process photosynthesis from the leaves to all parts of body and by this xylem the water reaches to the top of the trees too. But this pressure is not enough to reach to the top of the plant. So, during transpiration water loses from the leaves which creates a low pressure of water which in turn pulls the water upward.
